I am setting up another Lake Malawi tank and I got 5 of these guys (from a local store Chris and Carols living world pets in Kennewick, WA.) They are all about 2.5" and look great. This is a great community Cichlids, as long as you do not put them in with mellow fish. They can be aggressive but in with like Zebra's, lemon yellows, peacocks ect the do very well. The pattern of this fish is what first made me get them. It was a bit different from the other Malawi Cichlids I had seen. You can sex these fish when young by Venting them.
