Today I bought some Java Ferns and anubias nana for my tanks. I have plastic cobomba in the tanks now (which looks incredibly real), plus a "specimen" plant (plastic) in each. I like to keep the plant selection simple. I tied the java ferns and anubias to small rocks and the bogwood. I plan to buy some of the taller anubia barterii (sp?) later. I chose these live plants because I have read that they are less likely to be eaten by the fish, plus they are easy to move around the tank for cleaning, and can be removed for pruning, since they are mounted on rocks. I don't want to plant the tank floor - I like to vacuum that gravel! My question is, how long will it take for the roots to take hold onto the rocks/wood? Should I snip off the fishing line at that time? Also, the fish store said I do not need to buy any fancy lighting - the flourescents that came with the tank will suffice as long as they are on at least 12 hours a day. He also said that fertilizers are not necessary - the fish waste provides fertilization. I was surprised that he gave me this advice, since his store sells all those lights and fertilizers, etc.! I'd appreciate some opinions/advice from everyone! Thanks!
