I have quite a bit of plant in my new 60L tropical tank with 9 fish. Although the plant are growing well with new leaves, the leaves are small, thin and not looking healthy. The old leaves are not looking too nice either and they lost a bit of the green lush. I have a 11w florescent light that is on 14 hours/day. OK it is a study light but the tank is near to window. What can I do to improve the condition of the plant?
My plant types are hygropilia polysperma, hygrophila difformis, sagittaria subulata, rotala rotundifolia, cryptocoryne wendtii and roseafolia.
So far roseafolia is the only one that is doing well.
Thanks,
Sam
