No idea about the size. Person who posted the picture stated that they have caught it in a local river in Hawaii.

I would guess that it is a leucistic tilapia of some sort, perhaps Tilapia zilli.

Or more likely, it is a hybrid tilapia of some sort. Compare it to the fish in the left of this pic:

There are now at least six types of tilapia breeding wild in Hawaii.
