I've got a small Amazon sword and some Java ferns in my tank. I've got a good, bright light and the Java ferns are doing pretty well as far as dropped plantlets from old leaves but they haven't really branched out their rhizomes. The sword, which used to be big and beautiful, had to go through a heavy trimming last fall due to the death of the aquarium light and my lack of time to get a new one. Its leaves are bright green and healthy-looking, but the thing has stayed at about three inches tall for the past eight or nine months.
So I was thinking of using some kind of aquarium fertilizer, but I don't want to go around adding things to my tank that will harm my fish (Jack Dempsey, two convicts, and a pictus cat).
I don't know much about aquarium fertilizers...any suggestions?
