A few rams or other dwarf cichlids would do well in a 29. I also like the idea of it as a planted tank with a school of small fish such as tetras or brightly colored neons.Mine is also old. I've have him for about 3 years and he was full size when I got him so I don't actually know how old he is, but his red is fading and he's getting really lazy, not to mention going blind in one eye.Maybe go with the female sorority and some cories? Or rams and cories, rams are cool, the tiny dwarf ones.
Edit: although I don't know if rams can be kept in a 29g, may have to look that up.![]()
