White foam on coral frags

[JamesC]

So we've got a new setup and have had some coral frags in there for a few weeks now. One of them has developed this white foamy stuff on it though. Is this something we should be concerned about and remove? Or is it all okay?

Any help would be appreciated!

Sorry, no idea why the image attached upside down...

Welcome to the forum. The foamy stuff is a sponge, it's a good filter feeder to have in the tank, if you don't like it you can scrape it off.

Okay, thanks for the tip. I'll see how it gets on for now.
