Greetings, seeking help with identifying the algae/moss in the attached photo. Tank has a soil substrate, granules 1-3mm diam. pH 6.8 - 7.0 balanced. 25degC. Freshwater Tropical, lightly planted, artificially lit. Also any advice on limiting same - preference for predation rather than chemical interference. Cheers, Ross. (apologies for quality of photo due to small file size limits)
