It appears to just be green algae. Best natural way to manage it is a clean up crew of snails mainly.

Various fish will also eat it like blennys.

I don’t know what that is but I would imagine the best way to get rid of it off the glass is to scrape it off with a glass blade.

Mollies will also pick at the algae.

It looks like the typical algae that comes with a new tank. What kind of clean up crew do you have? I would get some more snails, small ones are better in my opinion likes ceriths.

I agree snails and algae eating fish will be a great help. Fish include lawnmower blenny, and a molly fish.

Thank you all !! I agree I wanted to manage naturally as possible and not add any chemicals , I have a just a few snails that my local fish store told me to add when I first set it up but I think I need to add more , any specific snails I should be looking for and how many ?

Is there any specific snails I should be looking for and how many for a 20 gallon do you think or suggest ?

I believe someone mentioned cerith snails. Nerite are also good, as well as nassarius.

 

[ejl2529]

For your size tank, 15-30 cerith snails would be good, they are pretty small.
