    Hello, i got some big leafy plants (dunno what name not nana), light green like lettuce. It was ok when i bought them from serangoon north (taiwan shop) ... but after 2 days the leaves at the edge are beginning to turn transparent, melting off ... what happened? ... what should i do to rescue them?

    should i add more liquid fertilizers? .. change water more often? is it the oto's chewing them up? please advice. thanks

    they are kept in a 1.5ft cube tank with 218W pl lights(10 hrs/day)

    Errr... Echinidorus (amazon sword plants), Aponogeton Ulvaceus? Look around www.tropica.com or www.dennerle.de catalogs.

    Some plants are grown emersed and the old leaves will melt when submerged while the new leaves grow. Cryptocoryne for example.

    Otos are not know to damage plants.

    Your tank is 25 gallons, but your lights is only 36W. That's about 1.5 W/G. Very low. For a planted, you should push it up to at least 2 W/G (low light plants) or 3 W/G (high light plants).
    That could be the cause.

    base fert? substrate fert? liquid fert? CO2? any other plants?

    It'll be great if you could id the plant... then we can tell whether the melting is normal.

    Is the plant showing any signs of new growth while the old leaves melt? Could be just adjusting to new tank environment.

    thats Nuphar japonica
    A distinctive plant - light-green leaves with transparent sections in the leaf margins. Most water lilies form floating leaves quickly, but Nuphar japonica can continue to form beautiful underwater leaves for many years. The leaves rarely acquire an algae coating, probably because they contain substances which prevent this. A nutritious bottom encourages growth. Often mistakenly called ''Spatterdock''. A beautiful and distinctive solitary plant for large aquariums.

    Yes, probably a good idea to add another 1 or 2 PL.

    Nuphar japonica may shed leaves at the beginning but as long as the rhizome isn't rotting, it will continue to grow. But it does NEED heavy root fertilisation, so putting some fert tablet or ball beside the rhizome is a good idea.
