I have 2 6"+ silver dollars and 2 6"+ red rooks for sale. They may be bigger but I haven't measured them, but they are about as large as they get. They are mature and have bright red spots on their bodies. Price is $25 each for the silver dollars and $40 each for the hooks. They are in my 750, I'm just thinning down the heard by selling the biggest ones. They are monsters and need a big tank. Local pickup only in San Jose, CA.
