I just recently moved back to hometown, in Southern IL, from Chicago.
There's a fish store, there, that has two 24" - 30" Blackedge in a tank...they've been there for over a year...they cant get rid of them. I thought about buying them, since all I do is highly aggressive tanks and even I wouldnt take them.
You'd get near the tank and they'd come out of the rocks, to the top of the tank, biting, trying to push the glass tops off. It wasnt cause they werent fed either...they were just that mean.
Morays are my speciality...if you have to have one, look into the Mexican Dragon or the Jewled Moray.
