Caleb, Snowflakes are Ocellaris and in a 225 they should be fine. I would wait until your tank is stable enough to handle the clowns and anemones. Even though I know you only have 3 fish in your 90 I don't recommend putting them in with your other clowns yet. I really recommend only one pair/tank but I have seen worst cases. 2 days ago I met someone with 6 different types of clownfish and 4 damsels in a 55 gal tank. That's a disaster waiting to happen.
As for the cost of snowflakes, are you sure they are not hybrids? I know of 7 pairs of snowflakes in C. Springs and they are all my hybrids. I have never charged anything for my hybrids, excluding trades. There is only one person I would imagine that would part with them, and given his situation I don't blame him, or fault him for selling them. However He knows I have given away over 100 of these hybrids to school projects throughout the country and he should not be taking money from any teenager for them. I hope I am wrong and you found a true pair in which case I have seen them retail for $350-$600. BTW people please do not PM,or email me, I have none left at the moment.
