Is bloat a concern with piscivores? Any bloatlike symptoms with these fish may be an entirely different syndrome and have different causes. One of the best ways to avoid nutritional problems is to feed quality foods and feed them in the proper quantities. Some people stuff their fish full every feeding and then blame the food they are feeding them for any problems. I feed less than the manufacturers suggest on their packaging. Rather than feeding as much as you fish can consume in several minutes, try as much as your fish can consume in one minute. Fish do not usually encounter foods with 35-45% protein in the wild-carnivores or not. Best thing about high quality pellets is color enhancement and vitamin supplementation if you ask me. You would be surprised how big fish can grow with small feedings. The resulting better water quality will help them grow out as well.
