Wow. Where'd that come from? It's a conversation. He brought up powerfeeding..therefore part of the conversation. Some folks offered some rationale input. I think we are all waiting to see what a "cavernous hole" looks like on a fish's belly. From the way it was described, I'm surprised it's eating at all. So once again...pictures?Congratulations to everyone who managed to derail yet another thread.. I'm sure there's more out there for you to offer your advice on - "that tank is too small", "you're feeding too much", "do you know how big that fish gets? I hope you have a pond" etc.
To the OP: I have NO idea what's going on with your Oscar but I'd love to see it (can we get a picture?) What're you doing to help it heal?
