Lost my 3.5" BGK today that I got from the Petsmart sale. Bummed about it too. Most aggressive thing in the tank. He was in a Cichlid grow out tank where everything is less than 1"! He was fine hour ago, and now I found him all ripped up and lifeless. Saulosi, Hyrbids, Yellow Labs, and Albino Metriaclima. Think I'm leaving the Knife thing for a bit, and moving towards Cichlids, lol.
