I JUST bought this Anubias from my LFS and attached it to my tank not so long ago. After some google searches about Anubias I realized that it is not normal for them to have these spots. Is this something I should worry about? I don't think it's algae because it isn't growing upwards, it seems to be a part of the plant. Also, all the leaves have this with no exception
Not sure if otos will eat green spot algae. I think they like the softer algaes and diatoms. Maybe remove the worst affected leaves and try to shade the plant a bit. I find that if anubias get too much light they're very prone to algae. They prefer a bit of shading from other plants. Posted via Mobile Device
try a regular magic eraser or a toothbrush to clean it.if that does not work you can let it sit in a 1 part bleach to 19 parts water for 10 minutes,then use the toothbrush and rinse well in water with a little extra dechlorinator. 1 part hydrogen peroxide to 10 parts water will work too.
