can I leave my 30 gal tank temp at 82º

[30gal4fish]

i have a yellow tang, a flame angel, soft and hard coral, and 2 shrimps.
I was wondering if they can adapt to that temperature. i did this for 3 days straight and i everything look normal.
any advise?

You can, but be sure that your water circulation, particularly at the surface, is good. Temp should not go about that, however.
