I have the perfect space for a 40 gallon breeder but I have no idea what I could do with it. I'm open to literally anything except saltwater and african cichlids except the tiny shell dwellers. The idea of a lone big-ish sedentary bottom dweller is appealing. I could do a shell dwelling cichlid tank. Make it a species tank. Make it a bio. Do a betta sorrity (wrong spelling). So many possibilities but the only one that reapply appeals to me is the lone bottom dweller so I'm looking to see how others would stock a 40 gallon breeder and maybe get some ideas. How would yall do a 40 gallon breeder?
