Are Polypterus cannibalistic

[JamesF]

neon tetras would accept others into their school even if they are small

Only up to a point. If they come across newly hatched fry, they will definately eat them.

I had 2-3" Congo tetras eat a bunch of cardinals...haha. Whoops.

The younger they are, the more cannibalistic they tend to be, pretty much the opposite of most fish. Plus, endlis are probably one of the most opportunistic from everything that's been posted. It's usually an endli or a lap that ate somebody's other fish.

I have never heard of a predatory species that wasn't potentially cannibalistic.

I don't think that is considered cannibalism
