New female betta: clamping fins and not eating

[otter]

Today I went to petsmart to get a few female betta for my sorority.
Most of the females where in little jars, but there was one tank in the back that had 3 female betta and a few cobra guppies.. live and dead.
I felt really bad for them and picked out the healthiest female in the tank, unfortunately, she has some kind of bacterial infection.

She won't eat and she is clamping her fins. She also is extremely skinny, underfed.

I tried pellets and flakes, but she wouldn't go near the flakes and spit out the pellets.

I put a tiny bit of salt in the jar shes in at the moment, and I also have kanaplex and maracyn.
There are no signs of bacterial infection on the outside of her body, so I'm guessing it's inside.

Should I treat her with either of those?

Sounds like starvation. You have to get her interested in the food like FFF.

Ok I will try bloodworms! Thank you for telling me so I didn't like accidentally treat her

[ChoclateBetta]

Yeah or it could be another problem so be careful. A Betta can go a while without food but it runes the immune system. You have a while to heal her so try your best and keep us updated.

Also, sometimes it takes them a bit to eat. Goblin didn't eat for a few days when I first got him, I'm going to assume its like that for females too. (:

Try to soak in garlic juice as well, I heard that is almost irristable for bettas.

Alot of times I find that they have trouble with the food. I have grow formula pellets and they go over fairly well. As do frozen blood worms.

You say bacterial infection? Just wondering what led you to that conclusion.

[otter]

Oh the reason that I say bacterial infection is because of the clamped fins.
All of the fish in that tank where acting that way so I bet that there was something going on in that tank. There where lots of dead guppies in it too, so thats what probably caused it.

unfortunately she died last night :(
