Java fern

would 4.2 wpg cause a jave fern's leaves to turn transparent? I am thinking of putting some in my tank.

If it is too much light then could i just shade it under something?

Java Fern doesn't have roots, it takes up its nutrients through the water column. As long as you have enough nutrients there, it shouldn't be a problem. If it turns black, it's possible that Nitrates are low.

Most "low light" plants don't mind being under high light, it's just that they can survive with less light, while high light plants can not survive under low light.

I have heard this plant in particular melts or patches of its leaves turn transparent under high lights.

Wasser,

You might want to be more specific about Java Fern not having roots because my plantshave many hairy brown roots dangling from the rioz.

I hear that they have roots too. I hear that the roots attach well to rocks and wood and need to be openly exposed to water. Also these roots supposedly hold the daughter plants onto the main one.

Sorry again, meant to do that in my reply, just getting there via long explanations.

Short answer: No.

Have a look at this thread: https://www.plantedtank.net/forums/showthread.php?t=4613

No they do not melt, but under high watt conditions they better have a GOOD supply of CO2 and a metric ton of nitrates.

jimmy,
Is the clear part of the leaf at the tip? If so, this is a sign of growth. The leaves should grow opaque over time.

i have 5.2wpg and I have flourishing JF right now.

JF seems to like cooler temperatures though. Mine died at 85-88f and came back to life at 78f.

that black crap that grows on the leaves will be gone in days if you throw in some Amano Shrimp. I am not sure what causes it though. My NO3 is always at 20+ppm.
