ID Please bubble type thing

[Twoddler]

Hi, was just doing some daily checks for aiptasia in refugium, when I so this bubble type thing growing on rocks in refugium. Could you please look and ID thx

Are they clear or green? Green would be Bubble Algae and clear would be air bubbles.
Cheers! Mark

If green, don't burst or you will have more.

If green, don't burst or you will have more.

That is an old untrue urban legend. Bubble Algae contain no spores to release when popped.
Cheers! Mark

Dose nt appear to be green yet more transparent

 

[Twoddler]

Thought about taking the rock out of the refugium but not sure if good or bad

 

[Daddy-o]

Do they pop like an air bubble? or do they have an outer membrane

 

[Twoddler]

Outer membrane, like some type of egg, just seen a black type creature with 6 or eight legs or more approx 3mm long run into the rock whilst I was trying so see if bubble or membrane, very strange, none in display tank that I can see, could nt get photo of preacher was to quick

 

[Twoddler]

I decided to remove the rock from refugium, if in doubt chuck it out basis. I so 2 black creatures, moved very quick, managed to video one of them move, centre, right of vid.... any ideas ?

Copopods, or even amphipods. Either are good to have.
