WHOA! Cooked food for fish??? everything ive ever heard or read says fish cant digest cooked food. But good additives are Kents Zoe, Brightwell aminomega, and brightwell garlic power is great. The garlic is very concentrated so if your fish arent sick or finicky eaters about one drop per 2 tablespoons of food is usually sufficient. Smell it first you dont want it to potent with garlic. And also be sure not to over feed this food and make sure your filtration can handle the excess waste. Shoot an email to Hans Discus(get it on his website) he has a great recipe that doesnt involve heating it.
