I think im going to get a dwarf lionfish and maybe a yellow tang and alot of crabs and snails and some shrimp. The tank is only 55gal, before I moved out of my parents basement into my condo I had a 125gal with a dragon moray eel a volitan lion a dogface puffer and a pink tailed trigger. But i was afraid to have a tank that heavy in a building so I cant go as crazy as i use too.
