I dont know what to do ,I have went through the cycle , now its fish time I have a sand bed of about 2 inchs , and about 15 pound of marshal iland LR . The thing is the fish I like , Triggers , large angels , lion fish , groupers stuff like that < I cant really have a clean up crew ,snails hermits , crabs , because these fish will eat them , is this right ? If thats the case how are you supposed to keep you sand bed stirred up , and cleaned of left over food ? :? All yeah this is a 180 gal. tank So can I have these kinda fish with alot of LR and cleaners , I guess that what I was getting at
