hi. I have two clownfish that I have had since they were only a few weeks old. They are now about a year old and one is signifigantly larger than the other. they hang out together and sleep next to each other and are i'm assuming a mated pair...unless the change of sex takes a longer time than one year. They are ocellarus clowns and I was wondering if they will breed or if it doesn't happen that easily. I know that if i have two females one will lay eggs but they will just never get fertilized and they'll just get eaten by the would be mother. and i know you need rotifers to feed the babies but i'm just wondering if it takes more time than a year and if there is anything else i could do. I don't have an anemone but i heard that one is not necessary.
