Microsorum Pteropus "windelov"

[ksam]

I recently added a nice clump of this to one of my tanks, attatched to bogwood. In the past 2 days I've noticed that some of the leafs have gone a burnt brown colour . I've got it in another tank & it's always a lovelly bright green colour so I haven't a clue what I've done to this one
The tank is in the middle of having it's lights upgraded so at the moment it's 2.5wpg (~20g tank with 50watts of light, so think thats right) it will be upgraded to just over 3wpg. The plant is partially coved by taller ferns (which are doing brilliantly) so I'm not sure if it's getting too much/little light.

I'm really not sure what's happened so if anyone could offer some opions that would be brilliant I can try & get some photos if needed aswell.

It probably means the leaves are dying off, which can happen. Just cut off the dodgy leaves and it should be ok as it settles. If you start seeing transparent leaf tips or black spots appearing that is a good sign as it means the plant is reproducing.
