Carnivore for Nano Reef?

[PringlesLFE]

I have finally purchased 20lbs of live rock and live sand for my 20G Long. I am still on edge about whether to do a FOWLR or Nano reef tank.

Either way, I have a ton of convict fry that are of feeder size and was wondering if there would be any suitable carnivores I could keep in the 20 long....possibly with an Ocellaris Clown and a few inverts.
Is this asking for too much? lol

one of the smaller frogfishes would be ok, but i doubt you'd want to keep your clown in there with him


just an fyi, the kinds of fish you're looking for are called predators
carnivore just means it eats meat, cardinalfish and grammas are carnivores that would do great in your tank... but wouldn't eat live fish
