well I plan to keep just those 12 all full grown.. but the azuls are yet small only 2'' in a 75g grow out.. got the NGT , Aro, and sharks together for now .. I wanted to know the answer to...is my filtration that Ive listed enough even though they hit full size...or will I need more? I do weekly waterchanges. I need to know if the 2 ac110, 1 emp400, 1 fx5 is suffice for their whole life
