Dragonets

[Dearth]

What are your experiences with Dragonet fish I have been considering taking a mated pair from a friend but I am leery because of their specialized eating habits and can be difficult to integrate into a new system.

My tank is very mature with a thriving population of copepods and amphipods what other things will they eat?

Are they jumpers?

All my fish are non aggressive but when it comes to sleeping arrangements I am concerned that territorial disputes will erupt.

Any other nuggets of info will be helpful in whether I take the mated pair or not I don't want to take them and then they die because I missed something
