I bought a pair of these at skiptons a few months back, i cant remember what they are either..lol. Unfortunatly one was sick from the time i got it home and it didnt make it, one is still alive and healthly. I feed it frozen brine, mysis and flake and it has tunrned fat and healthy, it does swim alot but it likes to have caves and hiding spots especially at night it digs itself into the crevaces between rocks.
