Update time.
finally got my driftwood, fertilizer and aquarium safe glue. Java fern is now glued to some driftwood (I did boil the driftwood first, did all the prep). Its now in a separate 10 gallon. I put it in there because I was worried the fertilizer might mess up with my tanks balance. Glad I did because it made the water very brown even though I put barely any in (about 1/8 of a cap full) I did see green shoots(?) or at least grass green bits from my Java fern so think thats good. Also when i pulled the rock wool off i found some golden yellowish balls. what are those? Seeds? Some kind of fertilizer ball?
Anyway hopefully it'll come back.
Though since my java fern is no longer in a pot and I did spend 20 bucks what are good plants that can live happily in a pot?
