Bubble algae - most people would recommend removing it, as not much usually eats it and it generally spreads quickly.

I have used a turkey baster to suck it out carefully

Agreed bubble algae. My Gal would love if mine grew like that. She loves large bubble algae but mine always grows in clusters of small ones never a single one getting larger. Emerald crabs keep mine at bay so now it only grows on the overflow weirs.

Emerald crabs have cleared my tank of bubble algae in the past as well.

Thanks for the reply.I have tried to manually remove it and it’s consistency is more like a harder shell and won’t let go off the rocks…I I haven’t tried to aggressively remove it yet for the fact I couldn’t identify it yet, or was worried I would contaminate my tank even worsening or spreading what was inside.

I do have a cleaner shrimp and and few different kinds of crabs but no one seems to be doing their jobs…
