Air bubbles in Cynarina?

[Abissus]

I have got this cynarina for a couple months, and there seems to be some air bubbles inside its polyp starting about a couple weeks in my tank.

Is there something I should do about it? It seems ok otherwise. Do I need to worry about it? I don't think the bubbles gottem more numerous or bigger.

Thanks.

that happens to mine as well. also it happens to a few of my candy cane polyps. it doesn't seem to hurt them and usually it releases in a few days. i'm curious to what causes it though and if long term it's harmful.

so i'm tagging along!

one of two reasons commonly:

excessive lighting (lights are too bright as with MH lamps over these low light LPS, or simply from mod bright lights left on too long)

or...

simply from the ingestion of food with air trapped in it (flake/pellet foods for example)
