| Sounds like common algae to me... Usually, vacuuming my gravel will turn it enough to make the algae not that noticeable. Some plecos get very large, so I'd do my research before I put one in. I think bristle nose plecos stay small for the species, but they still get rather large. Your aquarium is pretty fully stocked at the moment, and that's being conservative on the size of your Mollies. Actually, I'm surprised your Mollies aren't attacking the algae. Mine love it!
Unless it gets too out of control, it shouldn't bother anything.
An aquarium glass cleaner will get it off the glass for you. I use one every once in a while. |
