I have a problem with some new plants. I bought two batches of anacharis plants, one was older and had a few darker brown stems, the other had 3 young plants with smaller leaves and 2 stems that don't have leaves yet. My issue is the darker ones. The stems vary from dark green to brownish green and the leaves are all brown or brown and only a few left on the plants. I put them in my tank yesterday, and just now I saw my guppies nibbling on the dead leaves. Do you think the plants can grow back? I put some root fertilizer in the tank yesterday (bought the anacharis yesterday too) in the good news of the other plants, a few have already grown leafy buds! Perhaps it's the fertalizer? I also have a few floating on the surface, and plan to put them back later. Can anyone help me with my problems? I'd post pics, but I can't right now because I met the quota. I'll post pics once I clear out my other pics!
