I have two sabae clownfish.. one is bigger than the other.. i got them together from the petstore at the same time.. they have now been in my tank for 5 months. they haven't paired up yet. they don't even rec one another. they both do there own lil things in the tank like the other fish. is this normal.. or

Very normal- they often don't "pair up" or even mate; then only when they've reached maturity.
