Oh wait, actually it was the trumpets that I had a problem with. Not the ramshorn. Got a little confused there. XD
Anyway, trumpets breed worse than rabbits. Or shrimp in our case. And as I mentioned, if your water isn't perfect for those guys, they'll let you know with dead bodies everywhere.
Trained in EMS, I can save a person from death and/or injury. I cannot, however, save a man from his own stupidity.
