They look good and your Amazon swordplants look good too

The picture with the black widow tetra has a plant with some black stuff on it. It looks like an Anubias plant. Does the black stuff on the leaves wipe off in pieces or sheets, or is it really hard to get off the leaves?
If the black stuff wipes off in a film/ sheet then it is blue green algae (aka Cyanobacter bacteria).
If the black stuff doesn't come off and is like a fine short hair then it is black beard algae.
