What should I do to help my fantail goldfish grow back the lost portions of it's tail?

Question

The fish got stuck to the intake of a new filter on the tank. I have reduced the intake rate so no one gets stuck again.

Answer 1

You should not need to medicate the fish. Adding a medication for a fish that isn't sick is a waste of money, and can hurt your biological filtration.
Your fish's tail will grow back in time. Feed a high quality food to encourage growth. Add a little salt (1 flat tbsp / 5 gallons of water, disolved first in dechlor water) to keep away any infections that might take place.
Other than that, just clean water, good food, and time.

Answer 2

You can buy a medication called melafix at the pet store. Follow the directions and use it for a week. It will keep the fins from becoming infected and promote regrowth faster.

I use it all the time on my fancy bettas.

Answer 3

Aquarium salt helps heal infection.I've used it several times and it works.It is only about a$1.50 a box and is sold at all fish supply stores,also at walmart in the fish section.Follow directions and do not over apply.

Answer 4

Don't get it a pet piranha!
