Moss Growth And Its Effect On The Aquarium

[slowcountry]

Two of my fry tanks are in a position that receive indirect sunlight in the early afternoon hours. Within the last 3 weeks or so, tufts of a very dark green moss have started growing on the ends of the plastic plants as well as on the gravel. There is a slight buildup on the glass but it is not very bad. This moss looks natural and in a way has some beauty to it.

My question is that is there a negative effect for the health of the fish by letting it grow? Does this moss or whatever it truly is have a positive effect on the Nitrates as a tropical plant would have? Should I completely eradicate the growth or let it grow in its current state?

Sounds like black-brush algae. Harmless. If you like the way it looks keep it in, eventually is will spread and form a neat carpet look.

Yes, it does consume nitrogen but not much as it is not very large or a fast grower.
