Anubias what's wrong

[crystalview]

All my Anubias is sick with this stuff, some more then others what could be wrong?

My other plants are fast growing stems or moss and they seem ok. Is this because they are such slow growers? I was trying to use them to cover larger areas but give the fish a place to swim through.

The only time I have ever had trouble with anubias is when they get too much light -- mostly just green spot algae. I now put them in low-light (shaded or darker corners) areas in my tank. They grow slow, but they look good.

That plant is 20" tall the ones that are short (8") only seem to have the slight algae. I thought Anubias would grow in high or low light.
