My 20 Gallon tank is just about cycled and I have been thinking about stocking it with L. ocellatus and J. transcriptus which I think will be an awesome tank. I just want to know if I am missing something before I commit. Any thoughts on similar setups of a shell dweller and rock dweller that work well together gow about Altolamprologus calvus or compressiceps. Am I just asking for trouble? Should I just go for a single species of shell dweller in the tank and a pleco?
