Red Rainbow

[RyanR]

We got this Red Rainbow about 3 weeks ago.  He was doing great, then all of a sudden, his color got darker, he started hanging out at the top of the tank and stopped eating.  Last night, I moved him to a QT tank with a sponge filter and went right to the level 2 salt treatment.  My med trio meds are a couple of years old, so I decided not to use them.  Any idea on what could be wrong? Those are water bubbles on the glass on the QT tank.

Yes @Colu will help with this, and also waht are your paremeters @RyanR?

If you can isolate him that can help diagnose and see if he's pooping.  Is he passing any poop at all?  If so, is it white or stringy?

Thanks.  Sorry I forgot to include that.

Nitrate 25-50

Nitrite 0

Ammonia 0

I have 4 other rainbows that are doing well in a medium planted 40 breeder.  I don't see any poop from him, but I've dropped a few Extreme Nano pellets right in front of him and he won't even start to go towards them.

There aren't any spots on the fish, It's all bubbles.  When I get home this evening, I'll get a better picture without any bubbles.  His mouth will open about 2 or 3 time rapidly every 20 or 30 seconds, but I don't see his gills moving in rapidly.  I've always thought he was being a little picky with food.  Since we got him, he will swim around rapidly, like normal, for food, he'll eat a piece or two then spit it out, then actually eat another piece and so on.  I didn't mention those things before because I didn't think much about it until you asked the question.  We feed all of our fish a combination of Extreme Krill, Nano and Spirulina and frozen BBS and freeze dried BBS once a week each.  We didn't quarantine him when we first got him.  I ordered the med trio today, so hopefully I get it in on Thursday.

Spitting food out and loss of appetite can be a sign of a parasitic infection  another possibilities is it's colour change is down to nerve damage though it swimming in to something in the tank that very common in rainbow fish if you can get some better picture maybe turn off the air stone when taking the picture
