Just wondering. I have some growing in all three tanks. I keep it off the front glass, but let it grow on the sides and back. My betta and gourami like to pick at it, and of course the otos and gara pingi pingi feed on it.
Some algae can be considered desirable (what else would my poor little pleco munch on between cucumbers?). And some algaes can even be.. dare I say.. attractive? Yes, I dare.
