wow thats fascinating dragon warrior! see the thing is, they are really bad at the moment to the point of smothering some of the coral. Liveaquaria said they wouldnt be able to get one to me for about a month. I was looking for something immediate. Its a 12 gallon tank, and already tried a sixline wrasse, a friend's mandarin as well - no luck.
I guess if I found a small enough coris wrasse - however the tank includes 2 very docile bluestripe pipefish and an ocellaris clown that hasn't shown any aggression.
I'll give Dave a call though, thanks.
