Growing on my Glass
Flatworms. Hmmm. I think I have these guys in my new 75g tank. They're quite small, <1mm, whitish, and basically hang around on the glass, particularly in spots where the algae is not getting cleaned off on a regular basis.
What risks are there leaving them be? Are they more of a visual nuisance or is there risk of them wiping out other forms of small critters ie., if they are predators of copepods.
Will a 6-line wrasse help keep them in control?
