Bad day today

After I came home tonight. I found my Chocolate tang is stuck to the power head. Don't know what happen, I also have one other tang in there with him, but they been together for about 6 month now. Also I find out that my tank temperature is around 85F

After 6 month can they get aggressive and then fight each other to death?
Is 85F can kill fish?
This morning he still look health, but I notic that after I put the Rhomboid wrasses in the tank. The Rhommboid took his sleeping place and he have to move to the corner of the tank, but I don't think wrasses can kill tang right?

What do you guy think?



Right now he not die yet, I put him in the small plastic container and let it flow in the tank.
Tank temperature drop to around 80F right now.
Is he going to be ok or death for sure?
Now he not lay down on the bottome but he more like stand up position right now.

Thanks

Higher tenmps themselves arent the issue, its he lowered oxygen associated with it. Get some excessive flow (pointed at the surface) to ensure adequate oxygenation.

A tang wont get stcuk to a powerhead unless he is very compromised to begin with.

THe sick fish are the ones that get stuck to power heads. I think he was sick before that.
