corydoras is injured and pearl gourami problem again

[Meg0000]

Hello, one of my bronze cory has a small cut, it is hiding right now so I can't take a picture but I would like to know what I have to do. Also I am back to the same problem one of my 4 pearl gourami is hiding it's the smallest. I was away for a week so I don't know for how long it has been like this but the pearl gourami that I am talking about didn't eat today. What should I do?

 

[Meg0000]

The cory also has a bigger belly than usual
and there is actually multiple small cut at the gills area. It's probably hard to see in picture

For the cut I'd do daily water changes to prevent infection. For rest @Colin_T is needed.

Didn't we suggest getting another tank for the one being bullied?

I would do large daily water changes, until things clear up. (40% - 50%)

I gave the one getting bullied last time to my LFS and then I got 2 new pearl gouramis that looks like females.

Wipe the inside of the glass with a clean fish sponge.

Clean the filter if it hasn't been done in the last 2 weeks. Wash filter media/ materials in a bucket of tank water and re-use them.

Do a 75% water change and gravel clean the substrate every day for 1-2 weeks.
Make sure any new water is free of chlorine/ chloramine before it's added to the tank.

Increase aeration/ surface turbulence to maximise oxygen levels in the water.

--------------------
Add 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 (5 gallons) of water.

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, plants, shrimp or snails.

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.

When 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.

------------------
The new gourami is probably being bullied. If it continues to hide then return it and do not buy any more gouramis because the dominant one will kick hell out of any others you add.

Thanks a lot, I just bought swimming pool salt and will start the treatment.

My cory looks worst than yesterday and I got a better picture. It's not a cut, the cory is very sick and as I am writing it's floating at the top of the tank

[Meg0000]

Sadly I think the cory passed away I would really like if someone could identify what he had.

 

[Colin_T]

probably an infection from being injured.
