Going to petsmart today to get a heater and maybe some plants (or anything else I may need). I'm going to try to get this cycled quickly (filter media exchange, gravel in a mesh bag, etc) so I can get fish since I think we're going to my favorite LFS tomorrow. I want to see what they have there in the way of inverts, rainbows, cichlids, and even catfish. I'm worried about the checkerboards because I don't know if my water will be soft enough for them. Are there any other cichlids I could do instead? Or should I just do catfish and have no centerpiece?
