Green bubble spew...

[sweetfish]

I have a green bubble coral which is doing awesome, but it keeps putting out this red stuff, which I believe it does to warn off intruders. Not sure, but when it settles, it settles on my sand bed and I have to keep cleaning the sand and rocks it lands on. Any idea why it is doing this. I have had him about 6 months now and it is healthly and beautiful and loves to eat. There are no other corals or anemones right next to it. Thanks.

Could it be expelling waste?

I read somewhere that they expell a toxin when they feel threatened. I cannot locate the article. Did not know if that was the case and if there is no initial threat to the bubble I was wondering if I should move it from where it's sits. Not sure.

More than likely its waste,my brain coral does this all the time,usually a couple of days after a heavy feeding.

Sounds like waste to me as well. Almost all corals secrete toxins when threatened or even all of the time. However, these toxins are mostly invisible to the
