Bala sharks are misunderstood aquarium fish. These fish are generally peaceful and good companions to many other types of tropical fish. Bala sharks are widely available in most pet stores, but will grow to a size too large for the home aquarium. They are a hardy fish that will tolerate temperature changes, pH changes, and other factors to which other fish may be sensitive. The water pH should be 6.0–8.0. The preferable water hardness for this species is soft to medium (5.0–12.0 dGH). Water temperature should be kept between 22–28°C (72–82°F). The bala shark prefers to be kept in groups of two or more specimens. It requires a covered aquarium as it is a skilled jumper, but may injure itself on the lid of the tank.
Very young bala sharks are sometimes kept in small aquaria. However, given their adult size, schooling behavior, and swimming speed, the fish quickly grow to need much more room. Hobbyists continue to debate over acceptable minimum tank sizes, but generally recommend at least a 2 meter tank. FishBase lists a minimum of 150 cm (5 ft). Many believe the fish is simply too large and too active to be kept in residential aquaria at all; only enormous, custom-built tanks are acceptable, if any tank at all is. Indoor ponds are also considered feasible housing options and may be better suited to the average aquarist.
