Coral on Return Nozzles?

[treetopflyn]

I know lots of folks put corals on the rear glass and the overflows but has anyone ever put any on the return nozzles?

Thanks in advance

I wish I had a picture to attach, but one of my reefing buddies has a rather larger green birdsnest growing from one of his powerheads. He stated that it broke off the colony and got sucked into the head and just started to grow. It has got to be the size of a baseball. Its crazy! I'll try to get a pic of it.
