I recently bought 2 larger aquatic plants-not sure what kind-one has thick long leaves and one has smal rounder leaves. I put them into my goldfish tank and in a few days they went from a medium to lighter green to a little darker and they seem to be getting a little darker every day since. I have full spectrum lighting and I have added fertilizer and my nitrate level is about 30 ppm. What could the problem be and how can I fix it??
Plants getting dark???? Help!
