Looking for ID's

[xycose]

Sorry if some of these are obvious - I'm new

Looking for an ID on some things on my new live rock:


1 ) What's this orange guy? He appears to be able to move around

2) This is a bad picture, but any idea on this crab? Is he reef safe? I put him in my sump for now.

3) Is this just a red sponge, or what's this? I have a few of these

4) Pretty awful picture... but what's this purple stuff?

5) I put this shrimp in my tank, so I hope you guys don't give me bad news... Any ideas?

Thanks for the help!

Pic 2 ..... Crab.....trouble.....will attack slow movers, snails, fish, corals....
Pic 4.......decorator crab.........trouble.
Pic 5.....Shrimp, can't see his coloration clearly so if red back with white stripe....skunk cleaner and if reddish lines all over body, peppermint....both great for reefs or fish only provided the tank mates are not aggressive or large.

Thanks for the help Uncle99!

Anyone have any guesses on what the red thing is or the purple one is?

Here's a better picture of both, along with something crawling on the red thing, if anyone has any idea what that is either?

Red(with tiny critter?): https://imgur.com/a/ouKw9

Purple: https://i.imgur.com/tRJo64N.jpg

Also, a tiny urchin of some sort? any ideas? https://imgur.com/a/T37UJ

The red and purple stuff are sponges. I also got some with my tbs rock.

Thanks for the help allendehl, just to confirm, by the first one, do you mean the orange thing in my very first link in my first post, or whatever is crawling on my red sponge in my 2nd post?

Thanks! I hope i don't need to remove him, cant find him at the moment...

I meant this. A Florida conch.

I don't think is urgent but read about it. It's not safe. When you see it pull it.

Not clear, but I think that is a mantis shrimp. Not reef safe but could be fine in a sump.
