![]() ![]() This is probably due to their behavior towards conspecifics. There are no reports of Rainbow Wolf Fish being successfully bred in an aquarium environment. Although they can handle a wide variety of water parameters, they need a good filtration system with little to no water movement to keep them happy. Rainbow Wolf Fish are excellent jumpers and require a tightly fitting tank to prevent them from escaping. Smaller fish introduced into the tank will be quickly eaten, so be careful when selecting tank mates if you plan on keeping them in a community environment. One other recognized species ( Erythinus kessleri) that grows to a maximum length of 7.5″ is found in the Itapicuru River in Brazil and is virtually unheard of by tropical fish keeping enthusiasts.Įrythrinus erythrinus can be housed with similarly sized South American species in a large tank but because of their ferocity as adults, they are better suited to a densely planted, dimly lit, single species aquarium of at least 55 gallon capacity with a sandy or fine gravel substrate, plenty of floating plants, and plenty of hiding places in the form or driftwood or bogwood roots.Įrythrinus erythrinus are extremely intolerant of conspecifics and like male Bettas, will often fight to the death. Genetic studies of different populations have determined that Erythrinus erythrinus is a species complex and not just a single species. The strategy ceases as the Erythrinus grows into adulthood. Male Rivulus are attracted to the mimic “female” and are promptly gobbled up by the Wolf Fish. Adult females can be identified by their more slightly rounded bellies.Ī species of juvenile Rainbow Wolf Fish in Grench Guiana has a color pattern that mimics a species of female Rivulus Killifish. Although most Rainbow Wolf Fish have bone to white undersides, a Peruvian variant has a brightly colored orange belly. Their set back dorsal and caudal fins are brown tinged with yellow to reddish orange and their pelvic and ventral fins are translucent white to yellow. In general they have a light to dark brown body color with a wide lateral line that runs from the eye to the caudal fin. Rainbow Wolf Fish vary in color depending on locality.
