An update: 'Millie' the crawdad is now in the 60 gallon tank and hasn't been seen since the initial dive. This tank is a jungle. Halfway down she landed on a swordplant leaf and had a faceoff with 'Butthead' the Betta. (The kids named them.) 'Crusher' the crawdad is in his own 10 gallon tank. He likes to float to the surface and play dead. He likes bacon. TW
