Came in on TBS rock.

[BubblesandSqueak]

So I just saw this on some TBS base rock that’s been in my tank for a month. I am hoping that’s it’s a cucumber. I thought it might have been some type of sea star when I saw it had a uniform shape of legs. When I touched it it started to retreat. I believe this is just its head. It’s about the size of a golf ball with what I think are two antennae the size of my fingers. (Slug like). This was the best pic I could get so far from the angle but don’t want to do anything if it may pollute the tank.

I’ll try and get a better pic.

Doesn’t look like a typical cucumber.

Any ideas?

Ok.. so I’m looking under the rock where the other end would be and see this. Has a claw, and some sort of fan to catch stuff in the water. Blue and white video. Not ready to stick me hand in there yet.

I included what’s above it. Thinking two different stuff. Cucumber on top and maybe mantis but seems to have a crab style claw, not a shrimp style.

difficult to tell due to the blur. i can’t see the videos either. i believe TBS has a list of potential hitchhikers on their website

Bit hard to see in the photos. Does the brown thing have two openings? I have something that looks similar that is probably a tunicate.

they only show a red foot cucumber. That does not appear to be this.

Agreed, looks like a siphon. I have gotten lots of porcelain crabs on TBS rock too. They wave fans all day to catch food.

Try getting the phone closer to the subject and don't zoom. That's supposed to help improve these kinds of photos.

the two videos are a porcelain crab. cool little hitchhikers, we got like a dozen with our TBS rock.

I'll try that now. I believe there's a porcelain crab under the rock after seeing the photos. not sure about the top.

Looks like a galatheid crab or pebble crabs which ive seen in Florida waters.

Un zoomed. White lights. Looks like antennae, not tunicate.?

The shape indicates this is likely a tunicate.

 

[BubblesandSqueak]

Wish I had a coral viewer. Top down pic would be great. I'll shut the pump off and see if that helps.

Much better with pump off. Is that a claw sticking out the left side?

Dive mask, Mason Jar, some plastic kitchen untensile my wife lost all can act as a "viewer" to supply a calm surface to look through.

 

[KrisReef]

The latest pic almost looks like a Sea apple?

 

[Sesty22]

We're thinking that's a crab?

under the bottom of the rock there's a separate crab. on top of the rock there's something else. posted the clearest I could get above.

it could be a tunicate. It's pretty equally uniform if those are siphons. Not sure about the crab like leg thing. I'm scrolling through all the tunicates and stuff too.

 

[JoJosReef]

I'm betting tunicate. I have something very similar from my TBS rocks. I can't see from the angle, but mine has a larger siphon hole and a smaller in the back. They do pretty well as long as they don't get covered by anything. Valonia can stick to them and cover them up, so best to keep Valonia in check. Overall neat little addition to a tank.
