I have a72x18x18 tank set up for my poly/african oddballs, and want to add some live plants. I was wanting to use various anubias with possibly an african lotus as a centerpiece along with several large pieces of drift wood. What kind of lighting would I be able to use? Are there any other African low light plants besides the anubias and african fern? I originally planned on either to 36" single tubes, or possibly a 48" single tube. I want it to stay a low light tank b/c all of the species in it are low light loving fish.
