It may sound stupid, but its the size of tank I feel I can maintain right now, I don't want my fish aquarium to become more of a hassel instead of something enjoy, so I plan on slowly working my way up to larger size tanks instead of jumping right in becoming overwhelmed. Anyway, I love bottom dwellers, specifically catfish, and I would really like to start with one, but if I can't, then I can get one later down the road when i have a larger aquarium. =]
