Hello I currently have a 3.5in oscar and a pictus of the same size in a 30g I have a fluval 306 and some little hang on back filter(I think it came with a 20g I bought) for filtration I am currently doing a 50% water change once a week wich seems to be working but they cant stay in there forever. I found a custom tank was told it was a 90gallon I lost the piece of paper with the measurements all I can remember is that its 5ft long and I think its about 1.5ft wide but im not sure. Anyway I was planning on putting the oscar and the pictus in there. I will have sand substrate some drift would and some large plants(fake). For filtration I am going with the marineland c-530 and a Marineland Emperor 400 biowheel. I will still being doing weekly waterchanges. My question is what else could I put in? I only want 1 oscar in there to be the centerpiece fish. So could I have some other fish I love silver dollars and Geophagus taeniopareius but im open to anything.
Thank you
Thank you
