Have a 20 Gal tank with only the 1 F8 in it
He's just been brought home Monday from the store. And in hind sight.. the store I got him from was NOT good. Someone told me the guy was good with fish and I've come to learn quickly he isn't AT ALL. So illness wouldn't be a suprise. Adn the temperature was a LITTLE low this morning when I woke up.. at about 77.8.
I woke up this morning to find he had a red ball like protrusion from his anus. (Yea, at first I freaked out and thought he'd cut himself). But then I realized there was no blood or anything. Some of it has fallen off, but there is still some remaining. I've heard that red excretions can be from worms? (I have been feeding bloodworms on and off too, along with brine shrimp and krill) His appetite is just fine, he was continuing to eat even when I pulled the food out. He doesn't seem to be acting sluggish or frantic, just his usual behavior so far. So I don't know if it's just a normal excretion and I'm just having new-petowner jitters.
It seems from what I've looked at the only thing I can get here (in Canada) is something like the tank bath. He is the only one in the tank, so I'm not concerned with other fish or anything. But I have heard that the tank baths aren't the best? I have no problems with ordering stuff on the internet though. If anyone has some suggestions I would appreciate it.
This is the best pic I could get:
