Today (around an hour ago) I bought a clown fish pair. The pair consists of a black and white and an orange misbar, I chose different colors because I thought an inter racial clown fish pair would be unique. At first they explored the aquarium a bit but when i came back they were just hanging around the filter intake at the top where it is hard to see them. So my question is will they pair despite color difference and why are they near the tank and will they always stay there?
