You hit the nail on the head sumthin fishy. It's got to do with the melting temperature of warmblooded fat (melts at a higher temp because we keep our bodies at a higher temp) compared to coldblooded fat. Beefheart is standard practice for discus, but i think it's a holdover from the days when good seafood was harder to come by. Fish also cannot assimilate warmblooded fat as easily, and end up storing it in their liver which causes problems down the road.
