I almost bought some otos today, too. I went by Petsmart to see if they had anything I couldn't live without. They had otos for $1.49, so I figured I would get 4 of them and put 3 in one tank, and the other in the other (still following me here?).
I told the girl who was working there what I wanted. She seemed a little put out to actually have to do something, but reluctantly, she got the cart with the nets and bags. A couple of swipes later, she managed to net what must have been the 4 smallest otos in the tank! They had to be between 1/2 and 5/8 inch long. I told her that I needed bigger ones (3 were destined for my Altum angel tank) and she replied that they were all about the same size. I pointed out that there was a lot that were much closer to an inch long.
She sighed, glared at me, and then asked, "So what do you want to do?" I told her I didn't want $6 worth of feeders, so never mind. She dumped the bag back in the tank, wadded up the bag, grabbed the cart, and walked away. I'm not even sure she looked to see if they all made it back to the tank.
