Picked up some kp live rock - HH id's please

captain_jimmy · Jul 28, 2021

Hi there

i just got a shipment if rock in and have a couple things I'd like id'd if anyone can help.

A red crab.

This weird little guy is crawling around like a slug. Looks like it has two eye stalks at the front. Doesn't want to go above the water line.

Thanks all
Captain

Self reply.
I had been googling for ages before posting to ID that slug and finally found it just after posting. Typical, lol.

Looks like it is a leopard polyclad flatworm.

Critter Identification: Leopard Polyclad Flatworms – First Time Fish Keeper

Flatworms come in a range of colours, species, threat levels, swimming varieties, and some can look so exotic that you may secretly wish for an infestation. The Leopard Polyclad Flatworm, is not a species you would wish for in your aquarium.

Thanks for replying.

The top is the same as the bottom one but it's flipped over to show the underside.

The crab looks like a red Mithrax believed to be safe

check the crab to see if its male or female, the females are less likely to eat corals.

Thanks, searched r2r based on this reply and yes you are correct, it looks just like the pics in this thread...

Red Crab?

Ordered new live rock from Florida, and found this little red crab. Can anybody ID him and tell me of reef safe or not? Thanks y’all!

Hi

So I've been curing this stuff in a brute, it's producing a ton of ammonia, it's regularly at or above 1ppm. I've been doing daily water changes and dosing a bit of prime.

Couple other things have surfaced that I'd appreciate an ID on.

There was a yellow worm wriggling around the surface after I did a water change today.
You can see it silhouetted in front of the black.bit.of the heater.

I'd say 1" long.

It disappeared before I could get a better shot unfortunately.

What is this thing?!? It's slightly squishy...

There's definitely a spaghetti worm in there somewhere. I see tentacles retract when I shine a light in to the brute.

I've also been hearing a lot of clicking so it's possible there is a pistol shrimp hiding somewhere. Fingers crossed.

Thanks
Captain

And I just found this guy immediately after posting...

It's red and black. About 2" long.

captain_jimmy · Aug 2, 2021

Bump for the previous two posts.

2 types of worm and a weird sac thing.

Tamberav · Aug 3, 2021

The big one is just a bristle worm.

The small yellow swimmer... both bristle worms (and I believe eunicids) have a swimmer stage. Both can be found in a bright yellow as well.

I am not sure on the sac thing other then my KPA rock had some too and it was harmless.

Yep that’s a thing, it’s weird but it’s a thing

Does the sac have two big visible openings?

Might also be a sea apple. In which case great beautiful score but you need to watch out if it is dying, better to not have fish in the tank if/when it does. Would keep monitoring it for a while

can’t be a sea apple, they aren’t in the Caribbean. It’s a sea squirt
