Yeah, that was the skinniest of the three I got. They'd been at the fish store for over a month so I was hoping they'd be somewhat more resilient even though only one was really fat... they're eating well in my tank and have had veggies and algae wafers (plus actual algae) since moving in and are fattening up a bit. I didn't want to ship fish at this time of year (and get fish of unknown fatness), so I figured I'd take a chance on these otos... also better than the ones I saw at petco, which had three dead fish in the tank, two of which were otos. Thanks for the advice!
