Thank you so much for your input, so many helpful hands! Update, the sick piranha is in the corner staring outside the tank near the filter input, I tried turning off the filter input to insure he is not stuck but didnt move, still breathing even more hard to look at then before, here is a picture if helpful:

It seems like he is sleeping, any idea guys!?!?!
@owiain4 no i didnt i just dumped him in their with the 6 beacuse they hate the net, no possible way i could of gotten in the beast into a bag without him ripping it into pieces, big struggle getting out of the original tank and even some struggle into the new one, i wished i did though! Very depressing to see my fish in this condition!
