Hello all! I have a 40 gallon set up that i have running now with just assorted malawi cichlids (electric yellow/blue)im just establishing the tank with the two fish and then will move to my nephews 10 gallon. I want to go tanganyika, my question for you guys is what are some hardy fish to start off with? I eventually want to end up with frontosas, calvus and tropheus . Is this group even possible?
