How long do you think these guys were at Petco before I found them today? They were in a Petco aquatic plant tank. Can't get exact length right now but when I get how I'll measure them, I'm guessing 4 inches on the big one and 3 inches on the smaller one. I think it's pretty cool, I wonder if the fish staff were keeping them as kind of "store pets" until I scooped them up today while one of them was away from work lol.
