Well my name is Gilbert... we have a 44 gallon tank.... with pretty much not much in it.... my brother and i have been winging it for the past 2 months... currently we have a canister filter running... but i have heard to get rid of it... so we are working on a refugium... see if we can find one that can fit in a tight spot.... currently no skimmer.... we have a damsel that has been in there for about 1.5 months, 3 hermit crabs, 2 snails, 1 pointy snail, we have some sea stars and even though we havent actually seen the full brittle star, we have several inside the rocks...and today we bought a Green Wolf Eel... see how that one goes...
