my fish had fin rot and after treatment its whole tail fell off will it survive?

Answer 1

If you treated the condition so it's no longer present and there wasn't too much damage to the body, it should be okay.

If your fish is one that tolerates salt, adding a little to the water may help his recovery. Use a salt that doesn't have any iodine in it (aquarium, kosher, rock, canning, or pickling salt) and add about a tablespoon for every 5 gallons of tank water. (add the salt to some water in another container to mix it, never add salt directly into the tank). This amount won't harm most fish, and it can help in the healing process and help prevent infection until the tail heals. When you do a water change, try to replace the salt that's removed for a little while. The easiest way to do this is to take out water in multiples of 5 gallons. You can add the salt to the new water before you put it in the tank.

The very best thing you can do for your fish is to give him the best water quality you can. Keep up with tank cleaning and partial water changes (25% of the volume each week) so he's not stressed. Make sure the temperature is set to whatever is needed for his species, give him good filtration and aeration, but not too much current - it's hard to swim without the tail fin.

my mom had a fruit tetra and it had fin rot really bad and his upper fin came off then his body started to rot and it took about six months but he died. He did fine with no upper fin he only got sick when his body started to rot.

Answer 3

It depends how early you observed the disease and how do you treated. When it is observed too late, it doesn't help. But if you did in time, the tail will grow back and the fish will be fine.
