i bought 2 chunks of java fern today. i put it in my 10g with a betta, some neons and a bamboo shrimp. the lady at the store gave me some floaty plant for free. will the java fern grow quickly? is there anything special i should do for it? my lights are on a timer with about 16 hours on. i have an AC30 and a triangle sponge filter on the tank. also bought seachem flourish, but not really sure if i should use it.
