polyp

Just noticed this small brown thing with white/blue tipped tentacles on the glass of my NPS tank. Any clue what it could be? Sorry photos aren’t the best but curious if anyone recognizes this? Thanks

I have some firework clove polyps that have gone really droopy and the stalks are thin and can't seem to support themselves upright. The bases of the adult cloves seem to be wasting (?) almost. This has been going on for about a month. They have been sprouting new heads every so often which...

Hello All! my tank salinity was low 1.020 and over the period of two days i increased the salinity from 1.020 to 1.022 and then from 1.022 to 1.025. The first change was done by adding extra water and salt but for the second change, i took out water from the aquarium, mixed salt and poured it...

I’ve noticed that new polyps from different zoanthids are a lot less colorful then their “mother” polyps. What could the cause be? salinity: 1.026 Temp: 26.5 C ( 78.8 F) Nitrate: ~7 Phosphate: 0.04 Alk: 7 Calcium: 420 Magnesium: 1280 Par: between 75-150

I have two large Duncan colonies available that I have grown from single head frags. Both are balling types. Located in Las Vegas with shipping available. Each Colony has easily over 100+ heads but more like 150+ heads. Top colony (shorter polyps) $350 hipped Bottom Colony (Longer polyps) $400...

A little preface to my question So polyps are individual animals, separate from the corals themselves. Polyps not only house zooxanthellae but are the way corals interact with their environment by providing a means for the coral to eat food. Polyps secrete calcium carbonate underneath...

Anyone have experience with this stuff? About 3 days ago I noticed this white cobweb looking stuff growing on one area of a certain rock, since then it has spread to almost 1/3 of the rock. Started out real thin and loose, pretty unnoticeable, but all of a sudden it has started getting thicker...

BlueBerry Fields acropora Macroshot

Zoa is white and fades to blue. I’ve had it for about a month now, and it’s starting to get a little pink as well! Any thoughts? Thanks in advance :)

Hi everyone, Two days ago I noticed my hammer coral curled up, almost no polyp extension and really looking not that fluffy/happy... The next morning the situation was unchanged but I noticed some of the polyps had let go, or were letting go at the moment. Sorry for the bad quality picture, my...

Hi guys, after I read some threads it's still unclear whether I have enough flow for my acros or not. The problem is: I see no polyps extension at all, all of them are hidden (except one acro). I bought all the frags 5 days ago. Could such behaviour be related to reduced flow in my tank...

Hey guys just like the title says. My Acan has new fleshy heads all over but the other side on the skeleton this white thingy popped up, it looks like it retracts and is fleshy too, is this a sponge? The other heads are growing great, some of which are smaller than that white thing. What is...

It seems that the general consensus is that coral's zooxanthellae utilize nitrates for coral growth, coloring, etc. But on average, is there some sort of chart or general knowledge about how many nitrates corals can pull from the water in a given amount of time? For instance, One Polyp of...

I got this richordea about a week ago and i noticed this branchy thing extending from it. When i first put it in the branchy part would excrete stringy things sometimes. At night when the richordea does it's normal deflating inflating process over and over again you can see it showing a lot...

So the attached image is a frag that a buddy of mine who runs an LFS gave me. In the store they were listed as "Yellow Brick Polyps" They seem like Zoa's with a few noticeable differences, mainly being how tall/long they extend, and the length of the lashes. I'm just wondering if anyone has...

Noticed this about an hour ago, water is testing pristine, 1.024/1.025 not sure what this is, it’s about a week old from LFS, yet to epoxy to rock. Thanks for any suggestions or what this is and how/if treatable. Don’t want it spreading!! Thank you

I did some tank maintenance yesterday and temporarily got rid of my frag rack, moving my coral frags on to the rocks in the mean time. This morning I woke up and noticed the frogspawn had not opened (not surprised or worried, it probably doesn't like its new spot), however I did notice what...

Hello everyone, so tonight i decided to look further into why one of my zoa frags wasn't opening up all the way and came to notice these tiny and I mean super tiny little worms around the base of the frag. So I decided to pick up the frag and look underneath it and there were these small almost...

Hey guys. Noticed my Devil’s Armor polyps doing this the last couple nights. What the heck?

I purchased this from a live rock container and when i turned by blue light on it had a glow, can this still be alive???
