Red-tailed black sharks can be very territorial, and in a small aquarium they should be kept as a single specimen with no similar species. A far better way to keep these fish is as a large, rowdy group in a well-furnished set up in a similar way to some of the more boisterous barbs. Hiding places amongst rocky caves, bogwood and live plants will be very much appreciated. This primarily bottom-dwelling species mixes well with barbs, danios, rainbow fish and tetras, etc, that occupy a higher level in the tank. Despite their name, these are not predatory fish and will generally ignore small tankmates. Although it might seem surprising, considerably smaller companion species are more likely to be ignored as they don't illicit the same aggression. May look pale or washed-out in your dealers" stock tanks, but will darken to a jet black once settled into the home aquarium. An albino variety is sometimes available.
Water Parameters:
Temperature: 22 - 27 Celsius
PH: 6.0 - 7.5 PH
Carbonate Hardness: 3 - 18 DKH
General Hardness: 10 - 15 GDH
