I'm just looking for ideas. I have my 3.5in green terror and an 8in pleco in my 55, and I think that's all I'm going to have. I have my 3in Jack Dempsey in a 40L, and am going to buy a pleco for that tank. My plan is to in the future move my 40L population into my 90, that's empty right now. Don't think I'll put the JD and GT back together because they fought constantly. Any suggestions for companion with the JD or the GT, if I decide to add to that tank? Thanks.
