I had one for a little over a year(went from like 3" to about 8" in less then year). It was pretty cool. I did not realize how big they get and it would have out grown my 150 that I had it in. We unfortunately lost it during a move 2 summers ago. It was a steal and that is why I originally bought it. I think i paid like $50 for it... Either the store thought it was something else or just wanted it out of there before it ate everything... He was a big wuss though.. My Blue Line Grouper picked on it all the time and I had to put a divider in the tank...
