can you take the two chunks of rock out of the tank? if so I would take it out and deal with the calurpa fast. I had it start with one rock and it took over my tank :rolleyes: Lawn mower blennies are film algae eaters so no the will not help.

a couple ways to try deal with it are to put it in a bucket of water with a power head and heater.. put it in the dark for a month. or the extreme method would be to boil the rock for say 3 hours to kill everything off.

Cool! I just transferred my black spiny to the rough-and-tumble tank (he's big enough to handle it) and will try a tuxedo in the reef. I think they are beautiful, especially when you spot them with a flashlight at night.

I finally got so frustrated that I took the rock out and boiled it on the stove for about 1 hour. When I took it out, all of the caulerpa was still hanging on to the rock and I was scared that it would just recover from the ordeal when I put it back in the tank. I ended up leaving it in a bucket of diluted bleach overnight and then rinsing it numerous times. The rock is now as white and dead as a bone... but at least its caulerpa free!
