For a day and a half this guy's butt area has looked odd. Then today I discovered this thick white thing trailing out of it! Baffled and need some help, especially since this was a $250 fish!
There is now blood coming from his bottom. We've pulled him out and put him a hospital tank. Any ideas? Someone suggested he was compacted with poop.Sent you a PM on treatment options.
You can try feeding peas, but I'm still thinking internal or intestinal parasites.
Edit to Add: I was typing while you added above post. So sorry for the loss. I'd be going back to that LFS. That fish was infested when you got it. Again sorry.
