My two dats started doing the same thing 4 days ago. They wouldn't stop. All of the rest of the fish in the tank were fine. They just kept scratching and scratching. Then on the 2nd day, the thin bar got a film on him and the indo started gettiing red. I have them Q'd now. Rid-Ich, clean water and lots of salt. They are slowly improving. I'm not sure if it's a parasite or an infection.....I just know they're getting better. a lil
They're not eating though. That worries me. They always had such a good apatite.
