Is that the only place it is? If it’s only on a few leaves just remove the leaves. Cyanobacteria is a pain to get rid of but I’ve done it successfully with time and patience. I manually removed what I could on a daily basis and blacked out the tank for 3 days. I never add algae remover. If you ever go down the path of adding stuff like that, watch your water parameters as the dead algae can cause an ammonia spike if there’s a lot of algae to kill.
Yeah, that’s blue green algae for sure. I treated my tank with the ultra life blue green stain remover and it worked like a charm. In my case, my nitrates had dropped to 0 suddenly, so that’s what caused the Cyanobacteria.
People are saying “This is cyanobacteria”, but it’s a bit more complicated. This is an amalgam of algae and cyanobacteria. The algae appear to be providing a superstructure the cyanobacteria are growing on. When you look at “Algae” or whatever in a tank, try to imagine you’re looking at a forest instead of a tree to understand them better. You can look at a forest and see a lot of oaks, but that doesn’t mean it’s nothing but oaks.
In all likelihood mollies and shrimp would eat the algae. This *might* kill the cyanobacteria as it loses it’s home, or the cyanobacteria will just grow to dominate the biofilm instead. Shrimp will eat more of the cyanobacteria but still avoid most of it. They’re more likely to nibble at the unprotected edges and stop it spreading than to eat directly to the core of it – If you introduce them don’t be surprised if this lump sticks around but fails to spread further.
Raising the nitrates in the water will favour algae over cyanobacteria and can steadily lead to it being outcompeted, if you prefer algae instead. Your other plants will like it too.

Omg the eyes of those 2 tetras 😂😂😂

Looks like cyanobacteria, not true algae. Shrimp & snails won’t eat this. [Ultralife Blue Green Slime Stain Remover](https://www.amazon.com/gp/aw/d/B000QSK31M?psc=1&ref=ppx_pop_mob_b_asin_title) will take care of it & it’s safe for your cycle, fish, & inverts.
I got rid of mine with h2o2 and blackout

Less light should help 👍
I had cyanobacteria and put in water sprite. I swear algae is allergic. It all melted away in a few weeks.
