The ocean kind.

Seriously I don't really know. I'm in AU so I'd imagine somewhere off the Barrier Reef.

Is there any way I can tell what "type" of rock it is?

The damsel looks really nice and is so strong and healthy, but unfortunately he's just way too aggressive. It's a shame because he's one of my most valued and longest keeping inhabitants.

I have a 4 stripe damsel that I thought I was going to have to get rid of as he was pure mean. He adapted and I`ve had him for over 10 yrs now. Not all will adapt. I would even go as far as most wont. I sure hope it works out.

Keep in mnd the fish you plan on keeping also. If you have really active fish that like swimming room, or fish like flounder or sting ray that like an open sandy bottom, of course you don't want as much rock.

It's nice to have plenty of rock, but not like your system is not going to crash if dont have a pound for every gallon. So long as your filtration is adequate.
