Housing: The Red Tail Shark is a bottom dweller. They should be provided rocks and caves in order to stake out a territory. They do not harm live plants so you can use live or plastic plants. In an aquarium they are tolerant of standard aquarium conditions as long as the water is well filtered and partial water changes are conducted regularly. (Temperature: 74-80) (pH is 6.8-7.5) The Red Tail shark is known to jump so the aquarium should have a tight fitting cover. Small sharks can be kept is a 20 gallon tank. Adult sharks should have at least a 55 gallon.
Tankmates: Young specimens are peaceful community fish. As they grow they will stake out a territory and may fight other members of their own kind. It is best to keep only one Red Tail Shark, or one Red Rainbow Shark per tank, unless the tank is large. Groups of two are not recommended, but groups of 3 or more often work for a while when they are small. A partial list of tankmates may include gouramis, barbs, danios, rainbowfish, swordtails, clown loach, silver dollars, kribensis cichlids, corydoras cats, plecostomus cats. Adult sharks can be kept as single specimens with larger fish as long as they have plenty of hiding spots.
