Aiptasia, bubble algae, copepod and ?

The image was taken at about 5X zoom on my phone. Any clues on what the white thing is top right?

Hard to tell in the image but looks like it could be a sponge of some sort.

Man you really have it all going on there 😂

All in a square inch 🤣😂.

I wanted an Emerald crab anyway, guess a peppermint will be joining him.

Why not manually remove the bubble algae and aiptasia x for the aiptasia?

You can barely see either they are that small. That copepod is a millimetre at most. I didn't even know they were aiptasia until I put a PolypLab scope on it last night and zoomed a camera on this morning.

emerald crab and peppermint. both are cool.

So what I assumed were Aiptasia are actually some sort of tube worms. I have at least 3 colonies of them thriving in my tank.

Those look more like mini feather dusters than Aiptasia.

Just remove the bubble algae and you should be good to go. The rest are harmless.

I'd say hydroids rather than aiptasia - if you poke the stalk they're on, if it fully retracts to the rockwork it's aiptasia, but if there's a tube there it's not.  They do appear a bit like feather dusters, but my vote is still hydroids as the tendrils don't have feathers, really.

 

As for the thing top right, if it's also in the second picture, definitely a sponge.  Otherwise there's a chance of being a tunicate or maybe even a coral - would need a better pic or a description of feel/etc.

I know they aren't aiptasia after checking them out closely yesterday. They definitely have tubes. I'll check out hydroids.
