Starting yesterday, whenever I walk by the tank, the clowns start to wiggle in the goniopora. When they don't see my presence, they usually "host" the huge green nepthea tree in the back. The female wouldn't let the male in the goniopora so the male lodges himself in the zoas, and waits for the females to leave the goniopora. This new behavior is interesting to watch but it looks like the goniopora is not enjoying this. It normally expands twice as big. And I just realized that my biocube is all scratched up.
