Hi cam 191919,
I've kept the fish down to a minimum....where I dive for the "jewels" there are plenty of fish....lots of seahorses too,but they wouldn't suit this type of set-up.I have a pretty little goby,a triplefin and lots of shrimp,some porcelain crabs,pink and orange starfish and pure white nudibranches...also lots of turbo snails.....these all keep the tank "in balance"....it's always a temptation to overstock a tank,especially in my case where I can collect at will....I see you live in Florida,so you could probably do the same with a tropical marine!
