Male Clownfish got bit

[k_1]

Hi so I have had my tank for over two months now and I had started out with two clownfish. About two weeks ago one of them decided to turn female. And now about a week ago she bit my male clown fish and I have been keeping and eye on it but it's starting to look worse (It almost looks like he has a pimple on the side of him). What should I do?
