My Anubias Nana plants are the only ones in my newly planted tank that are forming yellow spots on all leaves. Ammonia at 0. Nitrites, Nitrates at 0, and pH is about 8. Tank has been up for about 4 weeks. 5 Zebra Danios have been in there since 3 weeks ago.
Any ideas as to what could be doing this? I'm running a low light, low tech tank, so there won't be any Co2 added and I have only 1wpg of light...sufficient for anubias. If I need fertilizers, what do I use and will it harm danios, rasboras, corys, and gouramis? I read some ferts may harm fish so I want to avoid that!



Any suggestions would be greatly appreciated!
