I have two "Raphael" cats, a striped one and a spotted one that I purchased yesterday from the LFS. They are about 1.5 inches long. Unfortunately, I had an impatient employee who didn't want to take the time to pluck "Ralph" and "Dotty" out of the nets gently and correctly.
I know the striped Raphael had a lot of bloody wounds on it's side and it's mouth looks a bit red. I didn't notice anything on the spotted one however.
The striped one is hanging out by the intake to the filter and I was unable to find the spotted one this morning. The tank has a piece of driftwood (hogged by a bristlenose pleco), a cluster of plants, and huge log housing a loach and a Featherfin Syno. I do not normally light the tank.
The water quality is good, I have two filters on the tank. I put Melafix in, added water conditioner that is supposed to help with the production of the fish's slimecoat, and also about a teaspoon of salt.
I will continue the course of the Melafix (6 more days), should I add more salt?
I put food in the tank last night, so hopefully they were able to eat.
PLEASE give me any advice as to help my new friends

Thank you in advance for all your help!
