I know it is illegal to buy and sell these guys anymore but my Mother-In-Law still has one from when you could buy and sell them. Pinky is huge and very bloated. She is also albino. Does anyone else around here have one of these guys? What do you feed it? Is bloating a problem?
*Info I know for sure about Pinky
She lives in a 50g tank all by herself, except for goldfish that are put in there as a self feeding device, they put in 5 or so at a time and they last her for several months.
She is also fed worms and shrimp I have no idea how regularly
She is also about 13 years old.

please note: i'm just curious about these guys and about what might be causing her to look like an overinflated balloon.
