New rock new hitchhikers!

[Extract]

Hey everyone. This is my first reef tank so I'm still learning what everything is. Any ID's would be great, but mentioning if they are good or bad would be even better! Thank you

1. Some sort of anemone?

2. A species of nudibranch?

3. Not the best pic but it was eating something and then ran into the rocks. Maybe a mantis shrimp??

4. Clam? I saw it move a few times when I went up to the tank.

5. Brittle Starfish, but it was pretty messed up from arrival of the live rock, should I just remove it?

1st picture is definitely an anemone that is an awesome score to get with your rock!

1 is an anemone - not sure what kind though.

2 doesn't look right for a nudibranch, but I can't tell what it might be from the pic. Any chance you could get pics of it from different angles, preferably closer up?

3 yeah, this is a mantis shrimp next to a bubble snail or headshield slug of some variety.

4 yeah, that looks like a bivalve (clams, cockles, scallops, oysters, etc.) hinge to me - so that's probably the back of a bivalve.

5 wow, that's in rough shape - you can try spot feeding it small pieces of food and see if it can eat; if it can eat, then it can likely recover over a few weeks - if it can't eat, then I'd pull it.

Thank you! I haven’t seen #2 since but I will post a close up if I see him again.

Will the mantis shrimp be a nuisance in the future? Also saw another worm like hitch hiker if anyone can ID it as well.

Will the mantis shrimp be a nuisance in the future?

Some particularly small, smasher species have reportedly been kept in reef tanks without too many issues (aside from the occasional missing snail or hermit), but it's generally recommended to keep them in a species-only tank because they can be very aggressive and very effective hunters.

To be safe, I'd get it out of the display and either put it in a tank of its own, put it in a contained space in the sump, or give it away to a local reefer or fish store.

Also saw another worm like hitch hiker if anyone can ID it as well.

Hard to say for sure without the head, but possibly Hesione picta?

Where is the rock from?

@ISpeakForTheSeas Thanks you've been really helpful.

Where is the rock from?

Gulf Live Rock. It's full of life and beautiful. Got a mushroom coral on the rock too but my phone doesn't get the pic right

So uhhh how hard would it be to eventually remove this lil guy lol. I definitely don't want to feed him any of the CUC I eventually add.

I'm not sure what the best removal method would be - some people struggle to get them out, others get them out pretty easily.

Some people see success with bottle traps or similar (see the link below), and depending on your tank situation (particularly the feeding situation), that may be a solid idea to try.

How to get rid of a mantis shrimp in my tank

Made me a harpoon and grabbed him a couple times thought he was dead but after 2 days he came back but he is a little smarter this time will not come out made me a stick with some fish hooks on it and a piece of grill but he will not even get close to it now any ideas would be greatly...

If that's not working or you want to try something else, then you could try some other ideas like pulling the rock it's in out of the tank or trying to remove it with a "shrimp gun."

Giant syringe/water gun to suction it out? I've seen these called "Shrimp Guns" or "Ghost Shrimp Guns" because they're commonly used to fish Ghost Shrimp/Mud Lobsters out of their burrows.

You can DIY one pretty easily with some PVC.

Given the current size should I start trying to trap him now? I do want him out eventually, but he’s so tiny I’m not sure if it would be effective at the moment.

Currently just fed the tank mysis shrimp once, to see the ammonia levels and if he was still alive in there. Well he sure was lol and hungry.

If you think the traps will work/aren't too big, then yeah, I'd try to get it out now (or after you figure out what to do with it when you catch it).
