My little guy is a blue/green VT... I came home from work the day before yesterday and he had a huge split in his caudal fin - right in the middle and nearly all the way up to his body, almost giving him a DT appearance. I didn't see any blood or discoloring around the split. I checked it out again yesterday morning and there was no change. When I got home from work last night, the edges of all his fins looked shredded and there was more shredding in some areas than in others. One area of his caudal fin was very shredded (maybe about 1/4 of an inch into the fin with just small strings of fin left) and I can't tell if there is any discoloration since the shredded parts are so thin.
I gave the tank a very thorough cleaning and soaked everything in the hottest water I could get out of my faucet. He's back in his tank now (moved stuff around in case he's bored and biting) and there were no changes this morning that I could see.
Would fin rot move that quickly and unevenly?
