Everything said above from Sol is correct on the cold water set up. Steve no longer has the cold water set up but did sell it to a local reefer Randy S. And best of all it is set up at Saltwater Fantaseas right now. There are some amazing creatures in it also. And as for the fish they are real neat to watch and also real expensive. If you do check out the tank I was told that everything except the fish came from the Puget Sound area.
