I used to keep only a 5 gallon tank, but I now have a 40 gallon community tank.
I had only java ferns until I had problems with them multiplying like weeds and ran out of people to give them to.
I put in water sprite, which is growing spindly (lighting not right?). I had ludwigia, which simply broke apart and stuck to the filter intake, so I threw it out. I also have a small amount of java moss, but have to keep it trimmed or it takes over, too.
I would like to have a beautiful fully planted tank, but I need advice on plants, lighting, etc.
