So I have in my 55g tank what I think is a tiger lotus, at least that's what it looks like (it grew from a black, hard round bulb and has large leaves), and some of the leaves look like this:




The leaf in the foreground has a mottled brown and white-ish apearance and a couple holes in it. The leave in the back has that degraded chunk out of it, but it wasn't eaten by any of my fish. I'm unsure why this is happening. I have almost 5 wpg of light and I dose the tank with a dropper of Flourish once a week. The plant itself seems quite healthy and is actually pearling right now. Could it be too much light? The damaged leaves are standing at about half the height of the tank. Anyone have any ideas?

How long have you had this plant for? What substrate do you have? Are there any other plants shading it? Maybe the light might be a little too intense, or maybe the substrate isn't providing enough essential minerals and viatamins...how are the ammonia and nitrate conditions? is this happening to any other plant too?

Arrow I guess since it occurs after the mid-section of the tank, it maybe the intense light that affects it growth and causing it to molt..

I've had the plant for a couple months now. These leaves were on the plant when I got it and were not in this condition. I have a gravel substrate on top of laterite, as well as Flourish and Aquarium Pharm root tabs which should still be good right now. Ammonia level is zero, nitrate is under 25ppm. The only plant that has shown a similar condition is some pennywart where a the occassional leaf degrades the same way, but the whole stems seem to be fine.

Yeah. I was thinking it could be moved to the side with less intense light when I re-scape the tank.
