Apres moi, le deluge!:

I guess I should say that I don't mind the giant Java fern but I don't know what to do with the 45+ fernlets growing right now! I am afraid this plant is too big for my tank... if it just fits, great but I am not sure about all those babies fitting in there, too.
I am looking for some Java Moss (online only) - I wold like to grow a carpet in there! I like the idea of floating plants but are they ok with the water requirements for killis (soft and black and brackish with low pH)?
This is a 12g tank. I will need something very low maintenance to grow mid-level.
And what about this brown algae problem?
THANKS!
PS - you can all have babies it you tell me how to get them off and send them!
PPS - You can see four of my killis in this pic! I just put on the black background a few days ago - it looks awful b/c I only taped it to see if I like - I don't think I like it on this tank - I can't see the fish very well.
