I need to confirm what I believe these two plants to be. Java fern and baby tears? The java fern was $1.99 for a 2'' specimen and the baby tears were $4.99 for a 4'' specimen. I just got them yesterday. They are in a 10gal with two 3'' comets. The comets are just in there until spring when they go back into the pond. They is 30 watts of flourescent lighting. Will they be ok with that? Should I use ferts and CO2 also?
