Crabs and Amenome ID

Got a little better pic of the anemone

Also noticed this thing...

And lastly, what the heck is this...he in on the side pannel of my peninsula, so you are looking at it from the top and at an angle, so you can see his underside reflected in the glass. Its probably 1.5-2 inch in size.

The second picture is that of an egg ribbon of some mollusk.
The last picture is that of a nudibranch. The tuff of tentacles in the top of the animal is it’s lung.The two dark spot in the front are eyes.

Sooo…do I need to get rid of one or both?

Beginning to think the egg ribbon is from the nudibranch…my wife said she saw it the other day up in the corner by the overflow, and there is another egg ribbon up there now too…

 

[Fiziksgeek]

Decided to take the first couple critters out.

I assume this is a gorilla crab "hiding" in the egg ribbon from the nudibranch or flat worm in the second pic. Either way, both are out of the tank.

 

[Fiziksgeek]

Still trying to catch this guy....

 

[Fiziksgeek]

Got another crab, not fuzzy, definitely different from the other gorilla crabs…any ideas?

Awesome, a useful hitchhiker! As a filter feeder, I guess thats why he didn't go for my crab traps....I was moving a rock around when I found him.

Definitely porcelain crab. Lucky!

Yes I’ve gotten quite a bit of rock from TBS and have gotten tons of these porcelain crabs!

this cute tiny urchin popped up the other day! Please excuse the dirty live rock holding tank lol

The sea urchin is great. He will continue to grow. The nudibranch is fine. Won’t give anybody any problem. He is a free living nudibranch. The last crab is fine. The first crab and the anemone need to go. The egg ribbon will just become live food for the tank.
these must be Gulf of Mexico live rock from Tampa Bay.

The porcelain crab has two appendages to filter small bits of food out of the water. Like net of a barnacles.

The nem is fine. As others have said, a lightbulb anemone. I got one in my TBS live rock too.

It might be an acro crab.

 

[Fiziksgeek]

Got another mystery crab…not a hitch hiker…this appears to be a freebie from TBS….it was bagged with the rest of the CUC I ordered…

 

[TnFishwater98]

Sponge crab?

 

[JoJosReef]

Decorator crab? If so, I'd put it in observation. They can have an appetite for corals like acans, blastos and super yummy scolys.

crab to me looks like something that can do some damage with the claws. Your preference on keeping it or not but based on shape and size looks to be a meat eater
