I am moving soon and I was wondering how I should go about transporting my fish. I have a 10 gallon aquarium that I just got with some black mollies. Would it be safe to use one of these critter keepers http://tinyurl.com/2e39ltk to transport the fish in? Or could I lower the water level in the aquarium and just leave the fish in it? It is about a 45 minute drive to where I'm moving to.
