DO NOT buy from Aqua Huna. I should have listened to the fish keeping community and not buy from this wholesaler. They sell unhealthy fish and clearly have not quarantined the fish before selling it to other individuals. All 30 of the green neon tetras I ordered died from epistylis after a few days in my quarantine tank. I gave them a second chance as the first time I received fish from them, they came with ich and all died off during quarantine as well.
One snail arrived dead. The other one is doing great. I don't think three days is enough time to know if a nerite snail is alive. It didn't smell until day 5.
