[tang daddy]

colt coral are very toxic same with leathers If you remove it from your tank make sure you do it outside your tank especially if it's on a rock also if you're ever fragging this coral have some tank water in a container and after fragging it rinse it off before returning it to the tank. If you have problems with the colt it could either mean you dosed too much of something or something stung it. Colts are the most hardy coral IME and was probally one of the first brown corals I started with never had one die but they don't like certain thing like too much flow moderate they love that's th only time I had a problem was when it wasn't secure after I elastic banded it to a rock it was fine.
