I bought a new Java Fern yesterday. I also bought a moon rock to attach it. I just tied them together w/ fishing line and this is how it looks.

I am planning to put it in my 29 g tank with 36 watts lighting. Is it enough for javafern?
I put them in PP for 15 mins yesterday. They are in QT tank now and treating w/ parasite clear. I will leave them in the QT for a week. Is it enough?
Hopefully my ranchus will not eat them.
Thanks.
