Tank compatibility[edit]

Keep with robust but peaceful tank mates. Do not keep with members of it's own species nor with other shark-like fish as the Flying Fox can be territorial.


Likes to eat algae when very young, but soon prefers dry flake food, bloodworm, etc. However, this fish will not resolve an algae problem.

Feeding regime[edit]

Feed once or twice a day.

Environment specifics[edit]

Likes a long tank with a moderate to strong current and bogwood décor.


Territorial. Doesn't like the company of other of its own kind or another of a similar shape like the Siamese Flying Fox or Ruby Shark for example. Should be fine with other fish otherwise.


Sometimes mistakenly labelled as the Siamese Flying Fox. It looks very similar to the Siamese, as it too has a black band runs all the way from its head to the end of its caudal fin. But this fish also has a distinct thin golden band running down its side as well. Fins develop a white flash at their edges. The False flying fox is also very similar but the black band ends before it enters the caudal fin and does not have the white flashes.
