cc stars

new to the board, this is only my 2nd post. I sure am glad I found the site, love it.
Question is this: ?Is it normal for the cc stars to hang out 90% of the time in the path of airbubbles?
Even when they feed on shrimps they end up by the bubbles, I thought it was deadly if they took in air

My largest cc star(Mr Jones) the other day was sooooo puffed up (center body) for about 4 hours then shrunk back down, BUT now has saggy body(points are tall and firm anymore). Dont have a good pic of him looking saggy. Posting a pic of him in the bubbles.
Thanks for reading my tread and any of your thoughts.

UPDATED PIC-Mr. Jones all saggy

Yes please, My powerhead makes bubbles, and I thought you wanted that for gas exchange.

It can cause stress for fish, but the big thing is it isn't as functionable as it is in a FW tank. The best gas exchange you can do is point a powerhead at the water's surface.
Ok, im understanding the functioning now. thanks

OK, mine ripples the surface but also makes bubbles. It isn't an airstone, it is an actual powerhead. An Aquaclear brand Powerhead 201. It has the ability to be done without the air tube hooked up, it just doesn't seem to do much more than push water around. Also, the HOB filter has a waterfall type delivery system which also makes bubbles. What kind of bubbles cause stress? The HOB filter does not make fine bubbles to speak of, but does make large ones that pop right up to the surface, and the Powerhead does make fine (what I would call microbubbles).
I read the link, but it only discusses airstones, not anything else. It also never got completed unfortunately. :(

I am inexperienced and easily way off base, but I saw an anemone do this once, and the LFS said it had excreted waste. Perhaps that is all your starfish is doing.

You actually don't want any visable bubbles in the display tank. I have 2 aquaclears as well, and you don't want to use that hose, as cool as it looks, its not a good thing. I would just aim one of those powerheads at the surface. It will make the water choppy, and does the same thing as far as gas exchange is concerned.

OK, I will remove the tube. What about the bubbles the HOB filter makes. They disipate instantly on reaching the surface , not gather like the ones in tecgirl's tank.

Please post specific tank parameters, how long you have had the star, and how often and what you feed it.

tank numbers are all great(right on), have never had problem with my water/tank numbers. the tank has been set up for about 9 months now and Mr. Jones(star) has been with us for about 1 month. He eats fresh shrimp, mysis shrimps, scallops everyother day and whatever he finds in the tank.
How will I know if he or others are not getting enough?
They all hang out on the wall of bubbles(which is coming out ASAP sounds like airbubbles are not good in the tank). Not sure why they hang by the bubbles, thought they must like the movement.

I don't know, but possibly they hang out there because the bubbles are the only source of oxygen if the powerhead is not set right - course I thought the bubbles were necessary too.

I realize your tank parameters may be fine, but please brag about it with numbers. What is "perfect" for fish may be fatal for seastars. A one month mark is a period of high mortality for seastars, so I would like to eliminate any possible issues with parameters.

Every star cc star I have ever seen goes to the top of the tank and will bend over and act like it’s reaching for something.
As far as the cc star blowing up and the deflating, I have noted this behavior only on the cc stars that are not getting enough to eat. I have noted mine and others blow up real big as they are sucking in substrate under them to retrieve nutrients from the sand or cc.
The bottom pic looks way too deflated and may not be getting enough to eat.
Ophiura, correct me if I am wrong.

So does anyone have a pic of a reasonably deflated one? Or are you saying it should only inflate and never deflate past the point of "normal"
