right now i have a really cramped 29 gal. i am planning on returning my fish to a nearby fish store, but what do i want instead? right now i have 1 JD, 1 Pleco, 2 African Assorted, and 1 Electric Blue Ahli. someone told me that exodon paradoxus (buck-tooth tetra) are a really interesting fish. i would like a fish that i can watch eat live food. are there any interesting fish you know of that can be kept in a 29 gal?
