I'm looking at my new Neon Tetras tonight, and counting them, and I notice one swimming oddly. Then I realize that he has no caudal fin! There is now a pinkish stump where his tail fin should be. They only fish in this tank are 7 other Neons. I have a small Whisper internal (hang on inside) filter, thats rated for 2-5 gallons, and because these Neons are so small, I have the water level quite low. I had the filter turned full bore, but after having a different Neon sucked up and killed by the intake, I turned it down as far as it would go. I also have a few snails in the tank. The Neon is still swimming, but it looks as if its in pain. Should I euthanize it or wait it out? I don't want it to be in pain. Please help, ASAP!
