Hey Bob (or anyone) what is this?
 

Bob, those zoo's I got from you are doing great! Just wondering what these bubbles are towards the back of them? I think these is 4-5 of them. New zoo's forming?

I am afraid not Walter. That is the infamous Bubble algae, or Valonia. I would lift the frag out of the water, and carefully so as not to break the bubbles remove them. Maybe use a knife point. :sad:

I got about 1/2 off without breaking them :confused: I rinsed it with some salt water after I was done and put it back in the tank. You might want to check your tank Bob! Those bubbles were on there when I got it from you... :razz:

Walter

I have them too. They are hard to erase. I have had some luck manually removing them :rolleyes:

Tweezers...

I was reading some old posts about it. Teevee was just poping them. Anyone know how that worked out?

My tangs eat them, but I think that's rare.

My yellow Tang likes them as well

Whaase I've only popped about five total and they weren't too big, but I haven't had any problems with them since. The bit of research I did indicated that whether or not they contain spores depends on their developmental stage... I would probably try to remove them without breaking them, regardless.

I generally try not to pop them on removal. Sometimes they just pop though by the time you get them off the rock. Whether they release spores or not just means you'll have to tweeze out some more down the road. But you didn't really want to have nothing to do though, right? Otherwise you might get bored. :wink:

My tangs don't touch them. Emerald crabs are reputed to munch on them, but I suspect they won't go for the real big ones.

I've tried emerald crabs a few times and unfortunately in my experience they just disappeared into the rockwork never to be seen again.

don't worry to much about breaking them they don't release spores acording to some of the big wigs on RC. I just popped all the big ones in my tank and the emerald crabs took care of the rest.

I have never had a single one. :eek: :confused:

You can have some of mine, they're purty :razz:

yup, bubble algae, or velonia.I just wait till there a little bigger and pic them off by hand. i popped one last week to see what it was. it looked like it was just full of water? :question:

Yea but you get all the aptasia :razz:

I prefer a few bubbles to the alternatives.

Usually a few bubbles are not a problem. When they start to multiply on a piece of rock with zoos, and push them out of the way, I have a definite problem. :mad:

I get the kids to pick them off =) they have nifty little fingers - I hope I dont need to get more of these little workers as the ones I have age!
