I plan to acquire either a 75G or a 90G....hoping for the 90G but if a LFS won't order me one I can just pick up a 75G from Petsmart. With that said I plan to put in some Red Head Tapajos either a group of 3-5, a Green Terror(I suspect to be female based on more rounded fins), and a Red Severum. Would 5 Tapajos be pushing the stocking limit in a 75G? I will have a Whisper 60 HOB and Sun Sun 304 canister.
