Come home to find a red mark/sore on one of my platys. The others are also quite skittish. It's unusual for them to be hiding.

I have melafix and primafix in the cupboard. Is it worth trying these?

I lost a Cory on Sunday but wondering if maybe due to these being new fish that ? readings are ok.
Ammonia 0
Nitrite 0
Nitrate is reading 10
pH 7

I also have a bristlenose in the tank so want to make sure anything I put in will be ok.

Looks to me like an injury. Do you have any aggressive fish in your tank, or any sharp decor?

Nope got rid of two male platys that were being a nuisance and a couple of guppies. That was a couple of weekends ago. This has developed today. No sharp objects or decor. Even got the fluval heater because it was fully covered to reduce risk of burns etc. Got live plants so no plastic.

Tank is 150l got 7 platys, 5 guppies, 5 corys and the bristlenose. Tank readings are in my first post. Got a fluval 307 filter so the one up for what was recommended so plenty of filteration. Air pump on 24/7. Water temp I have on 24.5

Just done a 25% water change as nitrates are usually at 0.

I’ve got an ich treatment in the cupboard but I know this is not applicable. Only others I’ve got is the melafix and primafix.

It just looks like a scale has been pulled out.

Do a 75% water change and gravel clean the substrate every day for a week.

And add some salt.
You can add rock salt (often sold as aquarium salt), sea salt or swimming pool salt to the aquarium at the dose rate of 2 heaped tablespoon per 20 litres of water.

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 4 heaped tablespoons 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.

concerned it might be more than a missing scale. Fish has been quiet since the weekend but this is the first day of seeing a physical problem. Also now just staying at the bottom of the tank.

With the julii corys and bristlenose salt still best over the melafix and primafix??

Thank you - not sure if this is a daft question. Should I still feed the fish tonight or give them a break tonight??
