i have 125g discus tank. i have about 5 large bushes of anubia nanas and i just got 5 anubia barteries with broad lieves. how many more plants do i need to handle my 6 discus and 4 flying fox bioload and compete with algae without putting too many plants in? also, i like anubias because i don't plant my plants into a gravel due to constunt uprooting and i don't feed my plants, also my tank is a low light. i do have algae present on nana leaves and the walls of a tank, brown and dark green to black. all algae is flat. i do 2 water changes per week. i just need to know how many plants i need without filling the whole tank with them? thank you. any other feed back is welcome
