I went hunting in my local waterways and only found worms, snails, etc. I decided that one snail I saw was pretty enough to try keeping. He was in extreme cold, around 45º, so I acclimatized him very slowly. Now he is in a 5g acrylic hex tank. I'm slowly adding water from the tank he's destined for, but what can I hit him with to kill parasites, etc., that won't kill him, too?
