I wanted to say something in the region of that, but didn't want to sound like I was going ott. Glad someone else agrees with me! Something like 6x3 footprint or even 7x3 with not so much height. With all those bottom dwellers and caves for those that need it, anything smaller and swimming space will be limited. Just the eels for example can potentially hit 3 feet. You also have a lot of near 12 inch fish in there (potentially). You might be better off getting more tiger loaches instead of one of your species- the more you get the less aggression there is likely to be, at least as far as the other fish go.
