I want to use some plants from our lake in the aquarium. I don't know much about keeping live plants, as this will be my fourth attempt, both with lake plants and store plants. The other times they just died. I have flourscent lighting on my tank. Its a single bulb. The tank is a 20gal long with two fancy goldfish in it. I'll be leaving the lighting on for 8 hours a day. I'll be using the diy yeast idea. I don't have any aquarium plant fertilizer though. I know I have to wash the plants carefully before adding them in the tank. Any suggestions?
