I'm a fish vet... again!!!

Well I'm nursing yet another sick fishy. This time it's Dory that's ill. He's got fin rot, and was *NOT* happy at all in his bowl. When I went to feed him on Monday afternoon, he jumped right out of his bowl and on to the kitchen counter. Well he was rescued, and his bowl and contents thoroughly scrubbed. He seems to be a pretty happy fishy now, and at least his water didn't get all cloudy right away like it did the last time I changed the water in it. I'm keeping a pretty close eye on him, hopefully his fin will grow back since I'm treating him with his betta medication.
