need to start a thread asking what I have to change in my chemistry to make my 7 week old hammers look like your 17 month old hammers... smile - and to the OP I agree they react more quickly to change in light, but so does one of my 5 torches - i.e., some population genetics result in different "behaviors"Ditto on the hammers retracting when the lights go down, and the occasional expelling of brown snot from time to time. Nothing to worry about. Mine started as 2 heads 17 years ago.
