Hey everyone! I had some hitchhiker a get into my tank from some softies I ordered. Luckily they are in my QT tank. I will explain the pics in order. Please let me know if you think you know what any of this may be:
(1.) This brown thing came between three toadstool leathers I ordered. It is growing and although it doesn't move around, if I go near the tank, mess with lighting, knock the glass or anything like that it retracts back and both large open holes on its sides will close up and suck in.
(2.) this white, tick looking thing I found today on a hammer that has died but I put it in My qt tank after cleaning it to try to keep the feather duster living in the middle alive. The white/transparent tick looking critter is moving around all over the place on this coral. Maybe it's what killed it?
(3.) This is a piece of Live rock that I moved out of my main tank to try to figure out what this is. The white, fuzzy things look like some kind of eggs? I have no idea. Then if you look to the left of it you will see a little green blob. I have found one other green blob in my main tank and am needing to learn what it is so I will know to remove it if u need to. The white fuzzy balls don't appear to be changing.

If you know what any of these are, please let me know adapter so I know if I can safely add them back to my main tank. Thanks!

Last one looks like pineapple sponge. They are good little filters. We have them en mass in the overflow as well as other locations.

The white or the green looks like a pineapple sponge? They are both on the same rock. I've never had sponges so I have no idea what to look for lol. Do you know what the others may be in the pics? Two are alive and moving

No idea on the first... What does it feel like? Some sponges take that shape. Second looks like a crab (xanthid perhaps) but that is not a feather duster... It is a barnacle. Third the white is a pineapple sponge and the greenish yellow looks like some other type of sponge.

The brown is a tunicate. The crab is a gall crab/coral crab.
