sorry, I don't think I want to bother with the hassle of shipping a live animal at this point, by the time you figure in shipping costs, extra money for the hassle, the mortality rate of shipped animals, you really would be better off looking at a Kansas City LFS in my opinion.
as for where it came from, I have no idea, but it is very colorful...I have had it for almost 3 years, so if the Singapore connection is newer than that I guess you may be able to rule it out.
as far as why its moving around so much, my guess is because it is trying to find a comfortable place. I have rather high lighting and high flow in some areas as well. the other BTA is in the best place in the tank as far as protection from too high a flow and also the only really decent spot where it won't get too much light...since the other BTA is dominating that spot, the clone just keeps moving, trying to find a good spot. he isn't neccissarily moving a great distance, he keeps going in circles, the problem is that the area where he is at is very near some corals that may sting or be stung by him...so far that hasn't happened, but it worries me, and I have too many corals to keep moving them out of the way...if the BTA had a spot to go to with decent flow, not too much light, where it could get snug and not threaten the corals then all would be well, but that's not the case so that's why I am trying to sell it.
