Green Sea Matt / star polyp

[Anonymous]

Sorry, don't have the latin names of them....but this happend to me twice, with two different sea matts in my tank. Here goes:

Every day, the polyps will be out and everything will be nice and full. Then, for no reason that I can tell of, they will close up for about 5-6 days. The following days, they will reopen as full as can be. This happened to one bunch, then about 3 weeks later, the other sea matt did the exact thing. They close up just enough to get me worried about water conditions, then out they come!

Anyone else have a simular experience? When this occurs every other creature in the tank is perfectly normal/healthy with no signs of stress at all.

Is something able to sting them? Also they like soft current so as to barely sway the polyps. This will keep dirt from sitting on them too.

I used to have that problem a few years back with them; haven't seen it in some time. Not sure specifically what caused it but I assume it has something to do with water quality. The best you can do is maintain good water quality, test for alk etc. Also keep some flow on them.

I had a similar problem when my PH and Alk were too high.

Ok, I'll check it out. The strange thing is, I have 4 different sea mats in the tank. All look extremely well, and are growing like crazy. If it was a water quality issue, wouldn't all of them behave the same way? Also, no other corals are showing any kind of stress either. I have Hammers, green, blue, red mushrooms that are all doing fine and appear very healthy, along with an organ tube (latin name in there) coral, that's growing really well too.

...one of these days I'll shoot up some pictures too.

Thanks for your input! 8)
