I brought these around 2 weeks ago. I moved them to my live rock. They were thriving. around 4days ago the polyp which is closed started swelling, so i searched on google regarding this and it was normal. But yesterday I realised there are some bubbles kind of thing on it. The one which is...

Are their certain corals that I can place near a pom-pom coral that will withstand the growth and brushing-up against? Thanks.

I have this odd brownish red round disk thing with a bright green center growing on a rock. Is the polyp or zoanthid?

Hi guys after an ID on this polyp. Brought it (cheap) a month ago and has been growing and opening well. Tonight I fed the tank like normal and within a minute it started closing up like an anemone.. Any ideas would be great. Cheers

Hello, I've had a colony of green star polyps for nearly a year now. They were originally a pair of tiny frags but now they've grown and fused together into one big coral. I love the colour and waving motion, so I'm considering letting them eventually grow on the back glass like this person has...

Hey guys, I got my new nano reef set up 2 weeks ago. I bought about 25 lb of live rock and 3 large colonies of zoas from a guy on craigslist. Everything is great except there is this mystery creature that I have found on a couple pieces of LR. I got a picture below. (sorry if they are poorly...

We just got our first marine tank (60L Boyu) and have been introducing life to it very slowly and things have been going well. We had our water tested four days ago and everything was perfect. So far we a peppermint shrimp, a pyramid snail, two live rocks, and our most recent addition; soft...

For those who followed me and my posts, some of you know that my 46 gallon aquarium has seen better days. My biggest concern so far has been the vanishing act of many of my soft polyp corals. Well its gotten to that point that only one Yellow Polyp coral remains in my 46-gallon. All other...

I've had it in for a day now and there isn't any sight of oolyp extension, not the slightest. My acro tenuis opened within an hour.

This is the one. Please help ID. I've searched sever sites/forums, with no clear results. What is this guy???

Which one is it?

Has anyone seen a white zoa/paly? Bought it like this at my lfs.

I have a small rock covered with what appears to be red and green mushrooms. There is 10+ on the rock and they look really crowded. Is it possible to safely detach them from one rock and glue them to another? If so what type of glue should i use and should i take the rock out of the water to...

I recently purchased a very nice frag from my LFS. It was about a 4 inch Y-shaped piece of rock which contained about 40-45 polyps. Not 100% sure on the kinds, but one was a type of zoa and the other was somewhat like a star polyp. I purchased this piece on Saturday. I had to return to my...

I've had my shrooms for about a month now, and one of them seems very happy. The other has always been a little sad. In the picture, the one on the left has nice polyp extension and sways in the current, but the one on the right just sort of sits there unceremoniously. Is it just because he's...

i was wondering what would be the best way to start a zoa garden in a corner of my tank... i have a couple of frags an mini colonies but I'm not too sure how id go about making these into a garden, if you could give me some ideas or better yet some pictures of your own gardens thatd be great! :]

I have an issue, see picture, with a zoa colony. As seen in the picture, one of the polyps has a strange shape/design. I'm trying to determine if this is an invader of some kind. Or, a damaged polyp. Within the past 10 days I gave the colony a coral dip bath and the colony looked great...
