Looking for ID on a few critters please!

Found these guys and have been monitoring movement and growth, but I am unsure if they are (all) aiptasia, and what the orange blob (stationary) might be.
Thanks!

Orange blob is a sponge.

The other is Majano. You want it out of you display tank.

Two choices: start a nano pest tank and toss it in (highly recommend it as it's lots of fun) or get rid of it.

Majanos should come off the rock pretty easily. The lazy way is bag it and leave it around a cold room for a day or two...it'll fall off. Otherwise, scrap it off or use a soldering iron and spot treat/cook it...

Don’t use a soldering iron on the rock while the rock is in the tank. That would bad and the majano wouldn’t mater anymore.

[emoji23] I definitely do not own a submersible soldering iron, so that was assumed.
I have successfully treated aiptasia in the past by injecting boiling water with lemon juice and vinegar.
Could I treat these the same way? Or are they really a threat? I could go either way with the tank, and stock with anemones if that would be an option.

It’s all about what you want in your tank, ive treated them with boiling water, or calcium injected into them. In one tank I didn’t even bother and they never spread. I’ve had friends skip treating and they took over the tank. Maybe it has to do with availability of nutrients?

2 picture is a sponge a very good resource for filtering and for coral/fish health
