Pearls can go pretty warm as far as water temp is concerned, but 30c is about their limit. I'm assuming you meant 80 degrees Fahrenheit, because if your tank is 176F, I'm sure they'd all be having problems! How long have you had them, and have you seen any signs of aggressive behavior toward the spazzy female from the others? Have you checked water parameters?

I hope you figure everything out before you go away *worries*

ETA: HEY! NO HIDING!!! ^.^
