Despite all I heard and what they told me at Aquadome.... Blennies are not reef safe. I purchased a Blue and Gold Blenny (combtooth) on Sunday... today I notice all my monti's, caps, leng sy, etc have what look like small scratches or patches missing... I looked and wait and saw the bloody fish just nipping away at them... it wasn't easy to catch him, but I finally got him and put him in an isolation net... probably going to dump off at RCA... now to get my corals to heal!
