ok i may be getting a bigger room soon upstiares and if i do i will prolly sell my 110 and get a 20/29 gallon. now for stocking, would 2 firemouths ( T meeki and T aureus ) work in there? thats all i will have for cichlids, and for other fish, a few swardtails ( already have like 8 frys growing up with my oscars ), 8 black skirts ( already have 3 ) 8 corys ( what kind? ) will be filtered either by my eheim 2250 ( so i can over filter it ) or get a AC 150. how does that sound for a 20 gallon or 29?
