What is this!!!!

[Mrfresh]

Got up to check the tank and found this.
I don't know if I will be able to sleep tonight knowing that's in my tank.
There's no way to catch it...

At ideas what this is?


His bottom side.

Really weird looking back side

Looks like it might be a crinoid squat lobster. They are reef safe and are usually found hosting in crinoid feather stars in the wild. Liveaquaria sells them for $20 a piece so nice score.

I have a few of them in the tank. I always see them but can't catch them.

So I just looked up that lobster, I'm pretty sure that's it, mines not quite as colorful but same body and everything

Reef safe as far as corals go yes. But watch out if you have smaller fishes then it's dinner time for the lobster

Seriously doubt they would be a danger to fish since their max size is 2 inches

Please do some research. Max size totally depends of the species. And since the OP's came in as a hitchhiker, the species is unknown. 60 genera and some 900 species

A lot of the time LA's "max size" is completely wrong.

That thing would undoubtedly eat a small fish. The key word is would, crabs/lobsters are opportunistic feeders. If they see an oppurtunity for a snack, they will seize it. No crab or lobster is 100% "reef safe".

I have done more research and they do stay very small. One site says .75 inches and another says up to 2 centimeters. This info was not from sales sites either but scientific databases. They are not a lobster but more closely related to porcelain crabs.
