Algae/Moss Identification help

[RxF 0]

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)

I have the Freshwater Algae of Australia book in my library but you would need a low power microscope. https://www.nokomis.com.au/product/new-books/botanical/australia-botanical/freshwater-algae-in-australia-a-guide-to-conspicuous-genera/

Or there is a basic cut down taxonomic paper https://www.researchgate.net/publication/233312467_Taxonomy_of_Australian_freshwater_algae_I_The_genus_Micrasterias_in_South-Eastern_Australia

Regardless of species, reducing light (duration or intensity) or food source will help assuming you dont want it. 

Or some of the suckermouth catfish. Hard or soft mouth species depending on what other plants you may have.

Hi and welcome to the site

Looks to me more like Cyanobacteria, which is not a true algae. Does it have a smell? Is it anywhere else in the tank? You’ll find plenty of info on google. If it is Cyanobacteria get some Chemiclean, only way to kill it.
