hmmm i had two baby red eared sliders that somehow always escaped their taller aquarium/tank. one day i came home and both were missing. I looked and found one under my bed. The other I never found. a year and a half later I see my cat clawing at under the couch and sure enough the second turtle was there.

If only my blue yabbie was as fortunate. earlier the same year my mom bought me an "AUSTRALIAN BLUE LOBSTER" because i had just started the hobby and was smitten with the creature. I had it a week and it ate half of my guppies and three or my neons. It molted and turned an odd brown-green color. I had it another three months and it molted a couple more times each time growing larger and returnng more and more blue. one night i wake up to hear my cat hissing at something. I threw a shoe at her to shut her up and went back to sleep. The next morning she has a little cut on her nose (probably got in a scuffle with the yabbie) but the yabbie was MIA. I searched and searched and finally found him in the bathroom (three rooms over) unfortunatley he was dred out and dead :(

I've also had a red claw crab and fiddler crab in an aquarium. they need a lower water line to prevent them from escaping and if need be seal up any openings with some window screen or wire mesh material to prevent the Houdini within them from preforming the great disappearance act!
