Where did this snail come from?

I was feeding my livebearers in my 20 gallon tank and noticed a large ramshorn snail in there. I have no idea how he got there. I didn't stock him and the only time I added plants they were from another one of my tanks. I don't have ramshorn snails in any of my other tanks. The only other snails I have are smaller pond snails. Anyone have any idea where this guy could've come from?

Snails usually come in on plants, although they can also come in with fish on occasion.

I thought about the possibility that he came in on some swordtails a friend of mine gave me. The problem is my friend swears he has no snails in any of his tanks.

if you added fish anytime in the last few weeks he could have caught a ride in the net when catching the fish

Most likely a snail egg
The spontaneous generation theory lacks scientific support. 8O

Hmm, I don't know. If I had ramshorns somewhere I'd buy that it hitch hiked from another tank somewhere. Since I don't, spontaneous generation seems plausible to me. I talked to the guy I got the sword tails from (the only new fish I've added to the tank). He swears up and down that he has no snails in his tank period. Says his BGK ate them all a long time ago.

No spontaneous generation. That theory was done away with ages ago and there really is no scientific proof to back it with.

Somewhere he hitched in with you. My guess is your friend thought that he had no snails but actually does. They can hide for a long time. I just found a ramshorn snail in my planted tank after having it setup for about 2 months now I guess.
