I bought a Tropheus duboisi for $25. When I got home I took him into the bathroom to pour in a net before putting him in my tank, because I did not want the pet shop water mixing with mine. As I poured over the sink, he jumped out of the bag and down the drain! I quickly looked under the sink at the pipes, and since they made an S curve I knew he was still down there. I ripped off my pipe and sure enough, the little guy poured into my hands. I then took him to his tank, where he lives fine to this day.
