Both fish will swim in the skinniest amount of water so if you had any hard rain events they could have swam from one BOW to another. Mosquito fish are live bearers so a single gravid female can populate a pond. If a pond has been dug in a wet spot in a field or a woods, if you don't sterilize the water before digging you probably have both in the water already and once the pond is finished, their population explodes..
