well i have an empty 30 gal in my garage for awhile now and been wanting to set it up again... right now i only have a 10 gal in my room with a betta and some tetras. but as for the 30 gal, i want to stock it with some predatory/aggro fish. i was thinking of stocking it with some small upper jaw species of bichirs with a few top dwelling fish... maybe an african biotope with a driftwood center piece. i;m up for any suggestions, so let me know of some ideas.
