I have a mature pair of ocellaris (over 10 years old) and a BTA they used to host in but are currently separated from. They currently reside in an Eclipse tank, maybe 12 gal, but need a new home. Thought they were going into a Biocube 14 but it looks like I am not getting that tank, which means my options are open! Do you feel 12 gal of tank space is too small for the pair? When they lived in a 55 gal they never ventured more than a few inches from their nem. Should I give them more space? If I went with a larger tank it could be cool. Maybe I could add a shrimp-goby pair, softies, interesting inverts. Tankmate suggestions? I have a Kessil 160 ready to use but could consider an alternative. Tank suggestions? It needs to be standalone, no sump, probably less than 3' long but I have not measured. A Biocube with no hood sounded appealing because it is self-contained and could house a little fuge in the back.
