Had the same scenario happen in my pond, a "friendly " put an unknown amount in and they spawned.....I have bass ranging from 3" to 6# now and having a hard time producing enough forage for them all to eat, my pond will be 2 years old this November, also have BCP in the mix(on purpose). All I'm trying to do now is make lemonade.. Good luck trying to figure out how they got in there
