has anybody else out there kept these before? they are quite interesting creatures. they are also called rubber eels, in case you don't know what they are, they are purple-grey in color, look like a big worm or snake, teeny tiny eyes and a big mouth. they aren't fish, they are amphibians. i had gotten a couple a long time ago but they got out of the tank and died, back when i didn't know any better to keep the top of the tank completely covered. they are very hard to find, but if you do and are able to keep one in your large tank, give them a try, they are cool.
