Over the past couple of months, the water in my brother's fish tank has turned a bizarre amber-red. He has neglected to do anything about it, since the fish are still perfectly healthy. While this seems to be true, the fact that our fish tank water is RED still makes me nervous.
The tank contains your average assortment of angelfish, tetras, etc, as well as a couple plants. It does have quite a bit of algae growing in it. Any guesses as to the source of this mysterious pigment?
