Right now I have one Blue Green Chromis and One Blk & Wht Chromis. I have been researching,,, AFTER ,I bought the damn thing. Most people don't realize that there are about three different kinds of Blk & Wht. Apparently I didn't get the good one ! The one that I have has black 75% of body with small black beady eyes. There is another species that is 50%. I have also seen another one more like mine, that is not really black, more dk greyish, almost black, w/ bigger blue eyes. I did look around to try to find out what their temperament was,,, I should have known, anybody selling it would not tell the truth. I really get tired of the BS. So I do never again deal with anyone who lies to me one time. I too agree with you on the Tangs. I have a small YT, when it goes they are gone !!! I may even try to catch it out too. But this black pig has to go !!! Don't buy one, unless you are feeding your Trigger :O) My trap is way too big, I have too many corals and it will break them. I tried to catch him tonight with a #28 Fishhook. But my Wrasses come running and I have to pull it out before they get to it. I wouldn't hurt them for the world. They are my babies. They come up to my finger in the water and bump it with their nose !!! I am just really disgusted with this fish though. I'm gonna try to build a smaller trap with a 1 liter bottle, I don't know, any suggestions ???
