Ok I have kept discus in the past but had to give them away because of moving purposes. I had 6 in a 90 gallon along with Sterbai cories and a school of Rasbora Hengeli. My question is I have just purchased many 29 gallon tanks and would like to devote one to a Discus pair. Is it possible? I mean I have never kept them in small tanks such as this one and would like to know how they would fair being in it. Dimensions aren't all that great 30"x12"x18". I haven't decided wether I am going to do Discus or Melanchromis Johanni breeding colony. Would like to shoot for discus but if not thats ok. Thanks guys!
