With such photo quality, it's hard to identify. It looks like Wallonia.

I would remove Valonia from the aquarium, but it's up to you. Here are the links to take a look.

How can it be deleted?

Collect by hand and discard. Young "buds" are firm and easily removed, while old ones are soft and may burst, scattering spores throughout the aquarium.

Mike

thank you for your help, I will delete it

The algae has spread over the stones, what should I do? Maybe someone eats it?

A little fox can afford that, but not all little foxes eat it.

Aquarium Resun 500, small will be for the fox.

Off-topic. Then there's nothing left to do but engage in selection.
