this is my 2nd congensis, not pictured so far, I mentioned above, that it wasn’t doing as well… it appears to like the new light over this tank, it has marked improvement the last month, since the new light… this is also a 24 inch deep tank, so it’s also a big plant , though no emergent leaves so far… this is also a soft water, tropical temperature aquarium, and it’s been here going on 2 years… btw… this tank has silver dollars in it, and they have left it alone… so far anyway… maybe because of the over abundance of available pothos roots…
