anubias is a very hardy and a slow groing plant. it looks like you planted the rhizome in the substrate which will cause it to die quickly. To prevent that, attatch it on to a piece of drift wood or a rock with fishing line. (heres a vid to help)
if you get too much light, it might burn the leaves of the plant so i would get a really weak light or maby not even get a light.
