I'm sure this is a very common question. Puck is my beautiful Crowntail, my college dorm pet, and I love him dearly. He's been back at home for about 3 months now, and I couldn't have had any complaints. He was a happy, wonderful little fish. About a month ago, I moved him from our dining room into my bedroom and found that he has a hole in the top of his fin. Now it looks like his bottom tail fins are deteriorating; could it be fin rot? I just cleaned his tank tonight very well; usually I do a half a tank cleaning every week or so, but today I cleaned it out fully, including the pebbles he has. Please let me know what to do! Pictures are attatched.
He isn't really spreading his top fin very much, so the pictures are the best I can do as far as the hole in it.... I feel like such a terrible owner, somebody PLEASE tell me what I'm doing wrong!
If the pictures aren't detailed enough for anyone, I can get new ones. Just let me know!
