Yes and no.
They are a strange fish, very aggressive towards each other as fry and then
they slowly become a cruising pack that doesn't really bicker.
Now I have kept them in brackish and marine.
In marine with moray, damsels, large butterflys, mono, large surgeon......
But that said when fed lots of feeders they are a lot more aggressive.
Fed pellets, most fish the same size are fine.
They really are like a little shark, built to eat small fish.
They grow dam fast too!
Very under-rated fish but yea think they rok da cazbar
Dam they can bicker when young tho!

Are Targetfish likely to kill others in a marine aquarium such as clowns?
