Woke up to a ripped caudal fin on Dumbledore. Unfortunately I didn't have time to put him in a hospital tank but I did get some water ready and a 1 gallon tank from storage and cleaned up. Question is, how much salt for 1 gallon? I added a double dose of Stress Coat per its instructions on the bottle. I have no idea what he could've ripped it on. He's been in this tank a month now, he he has been chewing on his tail, maybe he could've done it to himself? I don't know. I'm really upset.
Another question. The fin that he ripped, a strand of tail is still dangling. I will try and get a picture of it tonight. Will it eventually fall off? Any other suggestions are more than welcome.
