This stuff is accumulating on my rocks but I can't identify what it is. They're attached to the rock but can easily be blown off using a turkey baster. They don't move at all when on the rock or when you blow them off. I'm not sure if this is some sort of algae or what - can anyone help me...

I think it's aiptasia but not exactly sure and was wondering if any could help me identify it. Thank you.

While cleaning my sump/refuge, I came across an odd growth on some coral rubble I had laying down in the sand, the growth was growing into the sand, and under the rock was quite a bit of debris and waste that settled there. I am not sure what it is, though it is hard, like an sps, and it looks...

Is this a pencil urchin? It's about a centimeter in length. I've had my tank roughly half a year and my wife noticed this little critter running around my tank. It's been there the entire time, as we've had no new additions in many months.

hey! I don't know what algae this is and it is starting to grow like crazy all over the sand and glass! An identification would be greatly appreciated :) Water levels are pretty much normal

My tank is almost 2 months old now. Over the past few days I have noticed this thing growing in my base rock. It looks like some sort of fan worm, but am not sure. There are 2 of them and I have no idea how they got there. Any ideas?

Stuck to my liverock? What is it? Help please!

Can anyone ID this weird tube thing I have on my live rock? Is it fine to leave it or should i pull it out asap? I'm new to the reef scene and I have never seen this kind of thing before. :confused:

I got two of these type of starfish (or seastars) in Northern Florida, they have red bodies but the little spines (pokey things) on their bodies are small and skinny (as you can see in the pic) and the coloration is kinda pale? (it's dark right now so it looks pale or white or something) but it...

I am new to the hobby and had a chance to snap up someone's entire 110 gallon setup. It came complete with fish and corals. I've identified some mushroom and toadstool soft corals but there are three types of LPS coral that I can't identify. I'll post pictures of them and I'm hoping someone...

Not quite sure what this is. Some kind of mollusk? Thanks for your help!

My uncle has this coral and he doesn't know what it is. It is an acro of some type I think. He was told it is a hawkin blue enchinata or a Garf purple bonsai. Any help would be nice.
