Hello! I have had a new 20 gallon tank for a month. I have a gourami and some tetras living nicely together. (Purchased Mollys but both have died I think by stress from gourami who is territorial and chases adn new mollys I add) the tank ick a few weeks back and I treated it with salt which worked great!
But now I have noticed this brown algae in splatters on the rocks and coral. any ideas what this is? And is it bad?
