View Full Version : bird nest spreading?

03/11/2017, 12:11 AM
I have a 6 month old 40 gal breeder tank. I have noticed around 15 eraser sized colonies growing on various rocks and coral skeletons. The polyps look very similar to the pink birds nest I have and show the same coloration under actinic light.
Does anyone know what these are?

Do you have any Poccilopora? It is notorious for spawning in closed systems. I have babies on every rock, every plastic surface, and even on snail shells in my system.

It also reminds me of Pocci.
