I'm just looking for suggestions for one more species in my 55 gallon planted tank. Right now I have 2 SAEs, 4 otos, 2 panda cories (I'm getting 2 more) and 4 blue gouramis. I was thinking of Angels but I'm thinking I want something different since I've kept angels before. My pH is 7.0 and temp is 76 degrees. Any suggestions?
