Salvinia turning brown?

[FergusDaFish]

I have salvinia floating in my two tanks. In one it's green and healthy-looking and flourishing. In the other it's turning a reddish-brown. It does look like it's still growing though. Is this "sun burn" because it's much closer to the tank light? Or is it dying?

Has anyone else had this happen?

I need a pic to be certain but floating plants don't like much water flow.

Are your oldest ones brown or possibly the first ones you introduced to that tank? A while ago I brought home salvinia and it has produced a LOT, everything that is has produced is glowing green and flourishing, except the "mother" plant is brown. Still alive, still growing, still budding but very, very brown!

I imagine since I brought home a mature plant, it didn't quite acclimate to the light correctly, but its offspring is well acclimated and thriving...

So, is your lighting different in your other tank?
