Commensal acro shrimp!?
Anyone know what this is. I spotted it on an acro so I figured I would see if anyone else has seen one. It doesn't seem to bother the acro's. I'll will get more pics in the morning.

I have some sort of shrimp that came in my birds nest colony...looks and sounds like a pistol shrimp. Seems to be harmless, not bothering the birds nest or the crabs hosting the birds nest.

I posted about this type of shrimp over a year ago, and nobody really knew much about it.
I had an acro colony that slowly started to die from the base up, and when breaking it apart to try and save what I could, I found one of these guys. I'm not sure if the slow die off was due to AEFW or this shrimp. I didn't know much about flatworms at the time and think that was probably it. But on the other hand, the claws on the shrimp do look small enough to dig into the polyps of an acro. Here's the colony that I found it in And here are some pictures of the shrimp (For size reference, they were taken inside of a sports drink bottle cap ~2" in diameter)

I had one that looked very similar to yours. It was identified on another forum as a Coralliocaris graminea. It is a commensal shrimp and safe for the coral. I put mine back in the SPS colony.

Found this article on them.
Green Coral Shrimp Coralliocaris graminea Family Palaemonidae This shrimp (length 1-2cm) is an obligate on Pocillopora. Their two pincers have been modified such that they can produce a successive series of clicks when disturbed, like snapping shrimps. |

But my guess is they're similar to a small acro crab that hitchhikes in on coral that are taken from the ocean...most likely the maricultured corals.

they are safe, they are pistiol shrimp and they come on wild or maricultured colonies.

I had 2 in a mariculture coral that I got about a year ago now. The tank crashed and killed everything so I lost them . Anyways, I got a box of maricultured sps from java about 7-8 months ago and on one of the corals there is a shrimp. It doesnt look like the ones that you guys have in your tanks or the ones I had before but its a sweet looking shrimp..doesnt seem to harm anything so far. Mine looks more like a normal shrimp than lobster style if that makes sense!?

I got a tiny shrimp in my ORA SPS aquaculture frag. The frag is only 1.5 inches in height and have three branches. I cannot take a picture of this shrimp because it is tiny only about 1/4 inches and all clear. It has tiny claws and looks more like a fresh water glass shrimp but much smaller. I wonder how these shrimp get to these frags. I think they must reproduce by themselves in the propagation tank at ORA. I will keep a close eye on this shrimp and colony. I fraged the colony when I first got it and did not notice the shrimp at the time. The colony is going well with good polyp extension, so I don't think the shrimp bother the colony at all.
I don't think I can take a picture of this guy unless I pull him off of the frag, and I don't want to do this at this time.

I have one of these shrimp in an Acro. It is about 1" long from end of pincers to end of tail - maybe a bit longer. It creates a dead patch on the Acro where it sits. Has anyone else noticed this? First time I've had an Acro with a commensal shrimp - I'm surprised the wrasses haven't eaten it.

Nope, I didn’t say that. I was just very surprised to see an email alert saying there was a new reply to a thread I had posted in 9 years ago.
