Re: Trout in an aquarium.
Feeding them feeder fish is a terrible idea all around. Its a super way to introduce parasites and diesase to the fish. Plus bait shop fish arent bred in the best conditions or kept in the best water. I would avoid them as well. nightcrawlers, frozen food and pellets are going to be your healthiest food.
