So i have some coming in tommory. can i just drop them in the tank?
Perfect.I ship them wrapped in wet paper towels, inside a ziploc with air. If you receive them like that, you can unwrap them, put them into that ziploc and add just a little of your tank water to it, float it for 5-10 minutes, then add more to it. Another 10 minutes should be just fine. Then just add them gently to your tank by hand, lower them to the bottom. They will most likely just lay there for awhile, maybe 2 hours. Some say it takes a day or 2 but I've never had that. Don't assume they're dead if they don't move, they're stunned from traveling. BUT if you smell something bad when you open them up, you know at least 1 didn't survive the trip, discard quickly!
