I agree that the price isn't the best in the world. I've seen worse, though. Hammers are not hard to keep at all. I went without one for the longest time because I was told over and over how difficult they are to keep and how much light they need, etc, etc. I put mine in a 42-gallon tank with 110w of PC
lights (half .03
actinic and half 10,000K) for about three months and it never looked anything short of completely happy. Even when I was having some water quality issues and other corals were reacting poorly, this guy looked great. Now it's in a 92-gallon tank with perfect water quality, 110w of .03
lights and a 250w 10,000K MH
. It looks great.
As far as how aggressive they are, they do seem to reach out fairly often, but I don't know how bad the sting is. I make sure not to keep mine in close proximity to anything else. Hope this helps.
