Clowns grow to 4 + inches and hosting anemone grow to a foot or larger, the corals will grow and get stung by the anemone, the lighting will be too hot unless you take precautions and the water quality would be next to impossible with that bioload....impossible, especally for an inexperianced hobbiest and nearly for an experianced one.....
IMO, you most likely will end up just killing some beautifull animals....even if you start with very small critters, they will grow if their lucky enough to, but then what,,,,
