Hi everyone
I recently purchased a Salmon Tail Catfish to be a tank mate with my Oscar, they have gotten along great since I got him. Except today I woke up to find the Catfish Slime Coat was coming off. Went to my LFS and they recommended salt. which I put in. Now I've noticed 2 sores that sorta look like ulcers on each side of his mouth right next to his whiskers. My Oscar seems fine at the moment, and I thought the catfish might be stressed due to the recent move. If anyone has any recommendations that would be great. I don't have a spare filter otherwise I would of already put the catfish in another tank.
Ammonia - 0 Nitrite - 0 Nitrate - 20ppm
Attached is a pic of the catfish
Sorry this about catfish and not Oscar but just want a healthy tank
Thank You

I've no suggestions re the slimecoat or ulcers, sorry, I'm sure someone will have something to offer.

Your water parameters look fine but I have to ask; how big is your tank? Your catfish will be edging towards 3 foot long when it reaches maturity. Add that to a 14 inch Oscar and you have yourself a massive bioload requiring huge tankspace and filtration.

I have a 6ft x 2ft x 2ft, filter is more then capable to handle the bioload, but I don't intend to keep the catfish forever just want to keep him alive at this stage and not affect my precious O

i can not view the pic... it has private incription..

i have catfish too in my oscar community tank... and they are doing fine

Hopefully that link works, catfish is a lot more active today treating with melaflix, see how his tomorrow and ill talk to LFS,
I get a lot more complements already having him in the tank a lot of people don't see these catfish and they have a cool vibe to them hoping he pulls through

considering that catfish has minimal salt tolerance... just keep doing the 25% water change
every other day... it can pull through ...

The catfish is now showing White Spots, sure its white spot Disease, Oscar isn't showing any White Spots but is flashing around the tank. Not to sure what to do now, any medication ideas ? Regretting purchasing the catfish

poor guy if he does have ich you can try ich x

Thanks, ive salt dosed the tank and increased the temp, Oscar isn't showing any signs of white spot, acting a lil dosile but am treating with melafix still will update if they worsen or get better

UPDATE
Hey guys, so catfish has come good, no more white spots, swimming and looking healthy, Oscar is acting normal and looking healthy, thanks for your inputs and help.
