1 Polyp Inverted

[FBNitro]

I got a bunch of different Zoa's on the weekend, and they've been doing fine. Today when I got home from work I noticed one of the Polyps is inverted and doesn't close if nudged.

What should I do? The polyp is at the bottom of my tank, it could be moved up to the top if lighting would assist.

Does it look like a mushroom? if so, its just stressed or irritated.

It will bounce back, this happens a lot with some palys. Do you know if it's a paly or zoanthid?

I believe it's a Zoa (but I honestly don't know for sure... new to them).

Oh, I did a 2 gallon water change yesterday, forgot to mention that. SG is right at 35.

 

[FlaGuy]

If you mean that your sg is 1.035, that seems kinda high. I believe it should be closer to 1.025

 

[deluxe_noob]

i think he means his salinity is 35. Which puts his sg1.024-1.026ish i believe.

 

[FlaGuy]

Oops, my bad. I totally forgot about the other scale for measuring salinity.

 

[650-IS350]

Just looked stressed or irritated.

 

[FBNitro]

Okay, I'll just give it some time. It's still upset.

I guess the other question (related to this thread since it was asked) is, how do you tell the difference between a Zoa and a Paly?

 

[livingcorals]

Do you notice any spaghetti worms by it?
I did have a colony with a few acted like this until I removed the worm with a suction tube and tossed in the sand.

Zoa and paly...
Size of the individual polyp and stem. Palythoas a larger.

I did a 15 gallon waterchange to my tank and about a week later most of my zoas started doing that same thing. others are doing extremely well and growing, however, which is weird. a lot of my xenia also started dying and one of my SPS died. my ammonia nitrite and nitrate are all 0 and my ph is 8.3 and my kH is 16. is it the high kH? its the only thing I can think of... FBNitro, what is your kH?

I will try and get some pics of mine to show you how similar what they are doing looks.

I just noticed my pump to my fuge was practically off and the water was stagnant. It wasnt that way in the tank, but it makes me wonder if the tank was getting way less flow than it should have, and it obvious wasnt getting the benefits the fuge provided. I just fixed the pumps and swear the tank already looks better, will post an update.

My Kh is actually on the low side. I use meq/L, so I'm around 3meq/L which is around 7-8 Kh.

My one polyp is still inverted. Sometimes it looks better, other times it looks worse. Poor Polyp. Worst part is, those polyps I only have 3 of them...
