Quarentine first. How big is the sunfish? Observe the Sunfish very well since they are very stressed once taken out of the wild. Better if you could catch a baby instead of a med/full grown one.
If you put these two together, one of the following will likely happen:
Sunfish will stress and die due to inappropriate water temps
Sunfish will stress and kill piranha
Piranha will kill sunfish
Sunfish and Piranha will manage to kill each other

I have a weird story about piranha i was helped with a 265g that was built into a wall and had very little access room to get in. The tank had been community we were able to get all the fish out except 2 congo tetras. The piranaha came in so we had to put them in, their were 25 about quarter size. 8 months later the piranaha are 3.5-4 inch and they school with the congos.... they eat together and all seem very happy together but i still cannot catch the tetras.
