Aquarium Advice Addict
You see a reflection because you are looking at an angle or Australia is using glass with a reflective sheen to it.
As I said, I know smaller tank manufacturers might be using different glass on the bottoms than the big national manufacturers do. I have seen (and had) a number of different bottoms on my tanks from our local manufacturer but if it's clear glass, they should not be seeing a reflection.
We use plain old boring clear glass. We get reflections off the front, back and sides of the glass too. You see it in pictures that people take of their aquariums.
We will have to agree to disagree, but when a cichlid is displaying to itself in a bare bottom tank, it's seeing something.
