View Full Version : Only polyps in a certain part of stylophora colony staying receded?

Hi all.

I have a stylophora colony that I got about 7 months ago. I've heard they tend to grow slowly, but this guy's gone gangbusters since then, easily quintupling in size.

However in the last few weeks I've noticed that about a two inch section on two of the "stalks" have been staying receded.

This is confusing because I can't think of any reason just this section would be acting this way because, of all the reasons I can think of that polyps wouldn't expand (such as lighting, flow, pests, dirty water etc) wouldn't it affect the entire colony/corals around it (which have been unaffected)?

I did change around the rock work right before it started doing this. However I don't think it's any closer to the lighting, and regardless, different parts of the "stalk" are closer and those polyps appear normal.

Anyway I hope it's ok, I really love this guy and hope it's just one of those weird "oh yeah sometimes it does that for no reason" things that corals seem to have.[

I've attached a pic with the area circles for reference. In the pic most polyps are receded since it was nighttime and I only briefly turned on lights to get a pic.

Could it have grown and is itself blocking flow to the center of the colony?

No, my Powerhead is actually closer to the part in question. I actually thought it might be that since it's pretty close (too much flow) but it's not direct.

They do grow like gangbusters... anybody who told you differently does not know what they are talking about or does not know how to properly care for them.

This is probably pests. Nobody wants to hear this and nobody ever thinks that they have pests, but it is the most likely cause. It also could be from polyp nippers from the rocks below.

If you are a LED user, then it is possible that the new light from a new hotspot could be making it mad, but it should come out of this quickly if this is it.

I do have LEDs but I've had a sinking feeling that you're probably right. I've been trying to google stylo pests but have had no luck. Any ideas what it could be?
