hey planning to set up my next tank. i went to the lfs for ideas and in a tiny tank they had pom pom crab. they looked so cool. so i did some research and because of there behaviours i narrowed it down to a safe but equally interesting match. the plan is a 3 gallon critter keeper that i bought to use as a quarantine tank, it was never used still sitting there. i have a heater, tank, live sand, and live rock. i also have a 20 gallon power filter that im going to convert into a fuge with liverock and some macroalgae. will the 20 gallon be to much for this tank. i also ordered and odyssea super cheap 14in power compact that supposedly is 24 watts. either way it only has to be able to zoas. so do you guys think this set up will work, probably will add 1-2 blhermits. i dont think that this is overstocked. any opinions??
