I'm still just a beginning virtual gengineer, and my aquatic breeds aren't genetically programmed to use either of the swimming agents. For them, it's a learned behavior. Usually about the time they hit adulthood and their legs disappear entirely, they'll happen to swish their tails and move forward, and they're on their way to learning to swim. But it can take a while. Please be patient with them. Enjoy! Have a great CCSF!
