Hi all, I got one of these as a hitchhiker about 6 mo. ago and within the last 3, it has continued to "split" so now I have 9. They are green, 1/2 - 3/4 inches wide and look exactly like a mini BTA. I even target feed them once a week with either shrimp or squid, and they seem to love it. They stay in a small area and don't bother my fish or corals, and are actually pretty neat. Any ideas? Thanks!!!
