Raphael catfish turning red!!

Hello - my Raphael catfish is turning red and acting really weird! What could this be? I did a big water change and my filters were disgusting. So gave those a good cleaning.

I didn’t test the water before hand. But I have 2 and they both look sick. And the other one is hanging up at the top of the tank near the heater.

I added melafix, pimafix and aquarium salt.

Can't see the fish

When catfish or eels go red, it's just about always caused by poor water quality and a dirty filter.

You have cleaned the filter so that is good. you did one water change, which is also good. Now do a 75% water change and gravel clean the substrate every day for a week. Clean under the rocks and ornaments too.

You don't want any chemicals in the water unless you know what the problem is and this is most likely from water quality.

See how they look in a few days time
