RTN really means rapid...
By 9pm Friday night, the bird's nest coral was completely white. Man, was that fast. :(
It looks like something took a big bite out of the Hammer Coral. I wonder if it was the Urchin, as it eats coralline algae - calcium-based algae. Hammer corals have a calcium base that the polyps grow upon. I may have to remove the Urchin, as it does tend to knock over corals I care about.
I haven't seen my large bristleworms in the 29g's refugium in about a week. I wonder if I just am looking at the wrong time, or if the mud crab decided to make a meal of them.
In other news, the header picture is of a cubby system I built for a shop in Dallas.
