Watching my tank last night and noticed a small red growth on one of my rainbows (f) tails.

It looks like a bacterial infection but could be a tumour. How long has she been like that?

Make sure they are getting lots of plant matter in their diet.

Clean the filter if it hasn't been done in the last 2 weeks.

Add some salt to the tank. Use the maximum dose rate for whatever is in the tank.
You can add rock salt (often sold as aquarium salt), sea salt or swimming pool salt to the aquarium at the dose rate of 1 heaped tablespoon per 20 litres of water. If there is no improvement after 48 hours you can double that dose rate so there is 2 heaped tablespoons of salt per 20 litres.

If you only have livebearers (guppies, platies, swordtails, mollies), goldfish or rainbowfish in the tank you can double that dose rate, so you would add 2 heaped tablespoons per 20 litres and if there is no improvement after 48 hours, then increase it so there is a total of 4 heaped tablespoons of salt per 20 litres.

Keep the salt level like this for at least 2 weeks but no longer than 4 weeks otherwise kidney damage can occur. Kidney damage is more likely to occur in fish from soft water (tetras, Corydoras, angelfish, gouramis, loaches) that are exposed to high levels of salt for an extended period of time, and is not an issue with livebearers, rainbowfish or other salt tolerant species.

The salt will not affect the beneficial filter bacteria but the higher dose rate will affect some plants. The lower dose rate will not affect plants.

After you use salt and the fish have recovered, you do a 10% water change each day for a week using only fresh water that has been dechlorinated. Then do a 20% water change each day for a week. Then you can do bigger water changes after that. This dilutes the salt out of the tank slowly so it doesn't harm the fish.

If you do water changes while using salt, you need to treat the new water with salt before adding it to the tank. This will keep the salt level stable in the tank and minimise stress on the fish.

Few days at most, i keep a close eye on them with the problems ive already had. Ive just had a move around in my big tank so wasnt sure if she had caught herself on something.

I feed them goldfish flakes, omega one super veggie kelp flakes and duckweed so hopefully got plant matter covered.

Ill try the salt.

Thanks Colin
 
I agree with Colin. It’s red so it’s inflamed and not healing. I say bacterial infection. If it grows or worsens, you may have to use a med that treats bacterial infections. Try the salt and fresh water first. It can do wonders all by itself.
