I never thought I’d be this upset about a small inexpensive fish, but I am. The fish in question, a nine-month-old neon tetra, has no tail fins, since they’ve fallen off within the past couple of days :eek: I’m not sure what’s wrong with it, but it looks like a fungus, but it didn’t respond to fungal or ick treatments. Three months ago, or so, it developed a white sore at the base of the tail, and now, as I said, his tail fins have fallen off: the sore didn’t spread until a few days ago but then it did so quickly(I lost his tank member, who did not have any sores, this week as well). He still swims, surprisingly, with what’s left of his tail and his other fins but it looks like it takes a lot of effort. He’s also eating still.
Will the fins grow back if I can find something to get rid of his problem? Is he likely to be in a lot of pain(relatively speaking)? Would the kindest thing, as my mother suggested, be to turn off his heater and let him die? Hypothermia isn’t supposed to be too painful, and it’s not as though a vet could put him down. Suggestions please, I don’t want the poor thing to be miserable.
