I have a little problem w/ my new anubias nana petite, i have lots of nana petite in the same tank since i have that tank for about 2 years, those old one are doing well and green. About few weeks ago i got some small portion of nana petite from another member here, and i put in the same tank as my nana petite, but the new ones dont do well (yellow leafs).
Its 7.5g low tech tank w/ 13w cfl bulb in sand. i dose random fert everyday (comprehensive, iron, excel, n,p,k, trace....)
i need some input plz
I know that anubias turns yellow because of too much light.
i have black water, can barely see anything inside if few feet away from the tank. I dont think i have too much light, actually the one on the top (first picture) of the driftwood is the closet to the light which is more green.
