Hi,
I got this Spotted Hawkfish (around 2 inch) from a nice fellow reefer a few days back. Before putting in my DT I've placed it at the sump to test it's aggressiveness and unfortunately it was attacking my snails. So conclusion not for tank with snails, shrimps, etc. It is a very cute fella (goes near the glass when I open the sump door) but he needs a good home not a sump :-P
PM me if interested. Please pass me some Chaeto in exchange.
