New green barb tilted and hanging out by filter

[bazook]

Just bought a new green barb from local pet smart and noticed that my other 2 tiger barbs were nipping at it. I came home from work and found it hanging by the filter tilted forward at a 45 degree angle. I've noticed this tilting is kinda common during late hours but just lost a tiger barb to swim bladder problem and don't want to lose this one.

Params are good but I accidentally left my yeast bomb running for 8 hours...oops. Bought some peas incase I needed them. Advice?

Take the barb back.

I've read that it's quite common with barbs, although his swim bladder looks a little bloated, and his fins are going a mile a minute when he's not moving around. It looked like he was slightly tilted earlier also. I will attempt to feed peas in a few days and hope for a recovery, if there is anything wrong at all. I found a thread that dived into it a bit but it sorta fizzled out.

Petsmart guarantees their fish. Yes, it sounds like swim bladder issues. Let them take the loss.

Luckily I have a while to take him back, symptoms have calmed a bit, and I increased the pack from 3 to 6. He's one of two males and got picked on immediately by the larger male. I read it's also a common defense maneuver.

Since I forgot to add this I'll put it here...
29 gal
Ammo 0
Nitrite 0
Nitrate 25 ppm
Ph 7.0
The water was very soft about 4 days ago but the PH is up since then and I haven't been able to test the hardness

4 female barbs 3 of which are green
2 males 1 of which is green

This is a barb only tank, and obviously planted (hence the yeast bomb).
