I have a planted tank currently with some SAE's and Oto cats. I am looking for something med sized like a guarami (sp) sized fish to fill up the middle of my aquarium. the more color the better. its a 46 gallon. the lfs recomended discus but I thought they were only brackish. and what little reading i have done on them say they need water temps in the low 80's which i am not sure will agree with my plants or fish. eventually I want to have 6-8 yoyo's on the bottom in addition to the others. any help is appreciated. thank you.
