What size is the tank? What are your water parameters (specifically ammonia, nitrite, and nitrate)? What do you have for filtration? We'll definitely need some more info to help but it might be an easy fix.hi , can anyone help us we have got 2 fantailed goldfish that have had their tails nipped by rosy barbs, we have taken the rosy barbs out but the goldfish just lie on the bottom of the tank and ony move when its feed time..

Rosy barbs are actually subtropical and so don't require heated water .How big is the tank for goldfish? Goldfish require a ridiculous amount of tank space, COLD water (rosy barbs need HEATED water).. They should not be housed together again.
I'm not sure for goldfish (SASAMI may be able to clarify this) but you maybe able to use a bit of aquarium salt (NOT TABLE SALT bc it contains ingredients which prevent caking). And just keep the goldfish in super clean water.
It's been a thousand years since I've owned goldfish but for my betta who nipped his tail I used salt for 10 days and then kept his water clean and it grew back. Do goldfish eat foods other than flakes/pellets? If they are omnivorous-carnivorous try frozen bloodworms because they are high in protein.
***Disregard my response if Sasami comes with a different idea. SHE is the fish expert!!
Aquarium salt doesn't help injuries heal, it simply helps prevent infections and can also kill certain parasites. It's handy but not to be over-used. In this case, I wouldn't recommend it to the OP until we know more information .generally aquarium salt is recommended for helping healing. Melafix was also recommended to me.
