AqAdvisor says that this is a very aggressive species, up there with fish like wolf cichlids. In your experience, how true is that?

Paroon shark catfish?

Dovii are territorially aggressive and are likely quite predatory with smaller tank mates. PRS are not territorially aggressive, they have no territory, they are a free swimming, non-stop swimming fish. In terms of predation - I'd say they can be quite aggressive if left hungry with any tank mates, even the ones they cannot consume at all... they will keep biting them to death.

The half a year old black ear shark catfish duo: closing in on 1 foot, high strung and nervous rockets with amazing tails. Comparison to a 7 year old kin and to paroon shark catfish:

How are the others doing that was rehomed? I love the sharks activity level in that tank. Others are too lazy.
