Apistogramma rupununi: is it suitable for a community aquarium?
Apistogramma rupununi is a beautiful, peaceful, and inexpensive fish. I’d like to keep it. But is it too aggressive for an aquarium with other fish?
I searched the Internet for answers but found conflicting reports. The most knowledgeable reports were negative; this fish is too aggressive. But they were all made by people who didn’t own the fish. So what do they know?
How could I decide whether it would be suitable for my tank? I decided to investigate.
Apistogramma rupununi is one of the latest Apistogramma species to be described. It is described as “a peaceful Apistogramma that is suitable for the community aquarium.” This is not quite accurate. It is not a bad fish for a community tank, but it certainly isn’t the best choice.
The problem with this species is that it comes from an isolated stretch of river deep in the rupununi savanna of Guyana. The water there is clear and acidic; there are no other fishes present, not even any cichlids. This means that A. rupununi is probably more sensitive than most Apistogrammas to pH changes, water hardness, and lack of oxygen at the bottom of tanks. It also makes it less tolerant than most Apistogrammas of having its territory invaded by aggressive tankmates.
At first glance, this fish looks like it should be easy to keep. It is usually sold at a size of 2 to 3 cm (0.8 to 1.2 inches). It can live in water with a pH as low as 5.5, and up to 15 dH.
What is the history of Cichlids?
Cichlids are a very ancient and extensive classification of fishes dating back millions of years before, for example, dinosaurs. Cichlids probably originated around 550 million years ago (give or take a month or two 😀) and there are somewhere in the region of 2,000 to 3,000 different species, of which around 1,700 have been classified (at the time of writing).
Cichlids can make excellent community fish but you should take care because not all Cichlids are good community fish and may devastate an established aquarium, treating their tankmates as food, so before choosing a Cichlid, please ensure that you know whether or not your choice will be appropriate to your needs.
Apistogramma rupununi: from where does it originate?
As a hobbyist, I have been breeding Apistogramma rupununi for a while. It is a species from the upper Rio Negro in Brazil. Recently you find it in the hobby more and more often, even though it is not the easiest species to get along with. It needs soft, acidic water and can be rather aggressive towards its conspecifics. In the wild it forms schools and lives near rapids over stony bottoms.
I always wondered how this fish came to our hobby. That’s why I did a bit of research about its origins.
There are two main ways that fish get to our countries: either they are collected locally or they are imported from somewhere else. Collecting local fish is obviously the best thing to do. If you take animals out of their natural habitat, there will always be negative consequences for the environment you take them away from. However, sometimes the only way these animals become available to us is by being collected locally, so there is no choice but to do so. But if possible one should look for alternatives first. For example, seed collection could be an option for Apsitogramma rupununi because it has large eggs that are easy to collect without damaging them.
The genus Apistogramma is a group of freshwater cichlids from tropical South America. The group is divided into several sub-groups, the rupununi being one of them. This particular species is named after a river found in Guyana. It is said to be a beautiful fish with a yellow body and bright blue fins which can grow up to 3 inches long.
What are the basic characteristics of Apistogramma rupununi
All Apistogramsa rupununi have a yellow band on their tail and a red band on the upper half of their body. They are small fish measuring around 3 inches long. The males are larger than the females. They are omnivores, which means they eat both meat and plants.
They live in the water, but the water is usually shallow (under 10 feet deep). They can be found in small streams or ponds with soft bottoms. Some people keep them in gravel bottom tanks; others keep them in heavily planted tanks. The species prefers to live near rocks or roots where they can find shelter from larger predators like cichlids and barbs. They do not like bright light or strong currents.
The Apistogramma rupununi is an active species that spends most of its time swimming around the aquarium looking for food, although it will rest on the bottom of the tank during the day. It is not very picky about its food, but it does need to be fed some protein sources like brine shrimp, bloodworms, daphnia, tubifex worms and some vegetable matter like spirulina flakes every few days so it won’t starve. They require clean water so regular partial water changes are needed.
The Apistogramma rupununi is a very attractive little fish that is mainly found in the Rupununi River in Guyana. It is a small fish that usually grows to about 2 inches in length and has a lifespan of around three years in captivity.
The Apistogramma rupununi is a peaceful schooling fish that will do well in community tanks with other peaceful fish. The males are territorial and the females are not, so it’s best if you have one male per tank. They should be kept in groups of at least six fish, but the larger the better. These fish prefer soft acidic water with a pH of around 6.0-6.5 and a temperature of 76-82 degrees Fahrenheit.
What is the physical appearance of Apistogramma rupununi
Apistogramma rupununi fish description. There are two different types of Apistogramma rupununi fish. The first is the dwarf cichlid fish that is typically blue in color with stripes on its side. The second type of Apistogramma rupununi is a dwarf cichlid fish that is typically golden in color with stripes on its side. Both types of Apistogramma rupununi fish grow to be about 2 inches long.
Both types of Apistogramma rupununi fish are almost identical in appearance, but they are different species. The only difference between the two types of Apistogramma rupununi is their color and location where they live.
The gold Apistogramma rupununi lives in the South American country of Suriname, where it can be found in the wild growing up to about 2 inches long. The blue Apistogramma rupununi lives in the South American country of Peru, where it can be found in the wild growing up to about 2 inches long. In addition, blue Apistogramma rupununi can be found in large aquariums living up to about 2 inches long.
The Apistogramma rupununi is a species of freshwater fish in the family Apistogrammidae. The scientific name comes from the rupununi, a type of tropical rainforest found in Guyana and Venezuela. This species is popular among aquarium hobbyists who use this name to describe Apistogramma rupununi.
The Apistogramma rupununi is a small fish that has a white body and pinkish or red fins. The males grow to be between one and two inches long and the females grow to be between one and three inches long. This species is considered to be an omnivore because it eats both plants and meat, but it prefers meat.
What is the living environment of Apistogramma rupununi
Apistogramma rupununi is an interesting fish, but it is very limited in its living environment. It can live in water that has a pH of 6.5 to 7.0 with a hardness of no more than 5 dGH and a temperature range of 24 to 26° C.
It has been noted that this fish prefers areas with lots of rocks. The Apistogramma rupununi also prefers calmer waters.
The Apistogramma rupununi will have an average size of up to 2 inches in length. Its average lifespan in captivity is up to five years but generally around three years.
The Apistogramma rupununi prefers to spend most of its time swimming in the middle region of the tank. It also likes eating food that sinks to the bottom. They should also be kept away from large groups because they prefer to be alone and away from a crowd.
The best way to keep these fish healthy is by feeding them live blackworms and brine shrimp along with flakes and other types of frozen foods as a secondary source of food.
In the wide range of Apistogramma rupununi, which is known from the Rio Negro in Brazil to the Rupununi River in Guyana, there is a range of habitats. In the Rio Negro region, it lives in flowing waters and can be found near the edge of rapids. In the upper Rio Negro, where water levels are quite variable, it can be found either in deeper parts of lakes or near shorelines.
In other areas, such as at Apistokamma rupununi It has been observed mostly in blackwater environments such as oxbows and backwaters. The pH ranges from 5.8 to 7.8, with a temperature ranging between 18 and 24 degrees Celsius. It has been placed under different genera including Crenicichla and Nannacara, but it is now considered part of the Apistogramma family.
What is the diet of Apistogramma rupununi
The female eats almost anything, including freeze-dried foods that you buy at the pet store for your other fish. The males eat almost nothing rather less because they’re too busy trying to find a female.
Most of the time, the male hides in some small cave in an aquarium or pond, hoping that he won’t be seen by any passing females. Occasionally, though, he comes out to hunt for food. He has teeth on his tongue, which he uses to grab tiny prey like baby shrimp or infusoria (a kind of microorganism). So if you want to keep him alive, you have to feed him baby shrimp or infusoria or similar foods; not many people know how to raise these particular kinds of food though they are generally available from local stores.
Aquarists commonly breed Apistogramma species in an artificial environment. This, however, poses serious problems for the fish; in the wild, they are accustomed to feeding on live food. Artificial diets for these cichlids are available, but many aquarists find that their charges reject them.
The diet of Apistogramma rupununi consists of live foods such as blackworms (Lumbriculus variegatus), brine shrimp (Artemia sp.), tubifex worms (Tubifex tubifex), and bloodworms (Chironomus sp.). Their high demand for live food makes it important to maintain a good population of these organisms in an aquarium. Their need for live food may also indicate that they are less tolerant of water conditions than some other Apistogramma species.
What are the sexual differences between male and female Apistogramma rupununi
Male Apistogramma rupununi are larger than females.
The most important difference between male and female A. rupununi is the coloration. Males are blue on their dorsal side, which is most of their body, while females are black. Both sexes have a yellowish ventral side with no spots or stripes – this part of the body is called the chest.
Male Apistogramma rupununi have more intense blue coloration with a hint of purple, while females are more of a silvery color. The fins of both sexes are transparent, but males also have an iridescent blue edge to their dorsal fin that females lack.
Males develop their adult colours earlier than females do. This is most noticeable in young fish – males develop their adult colors before they reach half their adult size, while younger females do not reach their final form until they are mature.
Male Apistogramma rupununi are more colorful and larger than the females, and they have a little fin on their forehead which the females do not have. The males also have a modified anal fin which is used in courtship to present a nuptial gift of sperm to the female.
Males and females also behave differently. The female is also more aggressive than the male, and will often attack him if he gets too close during courtship or spawning. If she is not removed from the aquarium after spawning, she may destroy the adhesive eggs or eat her own fry.
What is an ideal aquarium size for Apistogramma rupununi
I set up a 10-gallon tank for my first Apistogramma rupununi.
I wanted to give my fish the best possible environment so I purchased a lot of live plants and driftwood to decorate the tank. They seemed to love it. After about a month I noticed that they were laying eggs on the plants and driftwood. The eggs would sink to the bottom and hatch within 24 hours.
The water quality was good and they didn’t seem to have any problems with ammonia or nitrites, but their fry seemed to be having some problems surviving. After several weeks I had lost most of their fry and was left with only one male and two females.
After doing some research online, one thing that came up several times was that “Apistogramma rupununi is too small and needs more room”. This made me think about what is an ideal aquarium size for Apistogramma rupununi.
I would venture to suggest that a 10 gallon tank or larger is preferred, especially if the tank is home to a community of species. Plenty of vegetation and rocks will provide cover and escape routes from aggressive species, but any particularly aggressive inhabitants should be moved to a different tank, if possible.
Are you keeping tropical fish as a hobbyist or as a breeder?
This is a question too often ignored in my humble opinion. If you are a breeder (either commercially or as a hobbyist who gives away young fish to other hobbyists) then you will need the resources to move fish into breeding tanks in order to maximize the yield of fry that will grow up either for sale or to give them away.
If you are keeping fish for the joy of observing them in something resembling a natural habitat then you may feel that it is appropriate to allow nature to take its course and, as and when different species breed, then many of the eggs (and surviving fry) will be eaten either by their parents or by other fish in your aquarium. This is the natural order of things because this is what will happen in nature. The fittest may well survive to reach adulthood.
If the species is large and/or if the species has a large number of young during a spawning then you need to have a well-established plan as to how you intend to manage what could be several hundred young fish at every spawning. Even your local pet store may not have the capacity to take them off your hands, even if they wanted to. This aspect of keeping fish is the most often overlooked but should be high on the agenda of all responsible aquarists.
Ultimately, the choice is yours to make.
How do you breed Apistogramma rupununi
Breeding Apistogramma rupununi is different from breeding other types of fish. The male will guard the female until she lays her eggs. If you have more than one male in a tank, they will fight for the female. It’s best to get a pair and keep them separate from other species of fish.
When you get your pair, don’t put them straight into the breeding tank. The water must be slowly changed over to the required temperature. This should take about a week. When you change the water, do it during the day when you are awake so that you can notice any problems.
Both the male and female may eat the eggs, once laid and fertilized, so it is recommended that the adults are removed to enable the eggs to hatch and the fry to grow.
How would you set up a breeding tank for Apistogramma rupununi
I would recommend setting up a small breeding tank, at least four inches wide and 12 inches long, preferably with fairly high sides and with fine gravel on the bottom. I would recommend using water from the tank that they normally inhabit so that their “natural” habitat remains relatively stable.
There is no hard-and-fast rule, but as Apistogramma rupununi is known to eat the eggs then it is recommended that both adults are removed once spawning is completed.
Is there a special diet for breeding Apistogramma rupununi
In the wild, Apistogramma rupununi feeds on algae and other plant matter as well as small invertebrates. In captivity, they may be fed a mixture of dried food including flake food and frozen bloodworms. The bloodworms are sometimes trapped in a net and fed to the fish individually. The fish should be fed once or twice a day.
A variety of other foods can be offered occasionally, including daphnia, mosquito larvae, tubifex worms or brine shrimp. A commercial diet specifically for breeding Apistogramma is also available; it is typically high in animal protein, especially eggs.
If you want to breed them as I do, they require biological filtration (live plants) and CO2 supplementation (bubblers).
As with many species of fish, Apistogramma rupununi may breed more readily when kept in groups. If the water parameters are maintained correctly (generally soft, acidic water) then spawning typically occurs within 6 weeks of their introduction to breeding conditions.
The Apistogramma is very sensitive to water quality, and any changes can lead to stress, disease, and even death. The Apistogramma rupununi is one of the most popular of the Apistogramma. They are beautiful fish, but it is sometimes difficult to breed them. Before investing in breeding your Apistogramma rupununi, you need to understand the optimal water parameters for breeding.
They are omnivores and will accept most aquarium foods, including flakes and frozen food. They should be fed at least three times a day in smaller amounts than other cichlids. If there is not enough food in the tank to feed all of the fish at once, feed only half the tank at one time.
