Hey all! I currently have a 30 long with two Yellow Labs (Labidochromis caeruleus) in it. I'm interested however in getting a slightly larger tank and attempting to set up a small community. Due to constraints set by my landlord I can't really go any bigger than a 40, and I was thinking that a breeder would be better after research suggesting the Malawi cichlids need more space on the ground to claim territory. I've mulling over the idea of the 40 breeder, combined with a 10 gallon turned into a sump, then stocked with my existing Labs plus some other fish. My reading suggests overstocking is the best way to go to prevent too much aggressive behavior. So my question is, what other species and numbers would you stock in such a setup? Is this a decent idea for a small community tank? I was thinking at least 2 or 3 more Labs and then an equal number of Mainganos. Would you stop there?
