Haha yea those guys are pretty mean! They never stop eating either. Ive had a snowflake with many fish no problem as long as he was well fed he really didnt care too much for the fish. I still have an eel in my reef. I even have him with a pair of green banded gobies and he doesnt bother them (yet). I should also mention hes a golden dwarf moray so I dont think hell really mess with any fish although every once in awhile hell eat my larger hermits.
