I've had the same thing happen with string cheese :crazy: It is funny when they are in a larger tank how upset they get being confined in anything. I have to sequester one in a breed-n-show in the corner sometimes if he's eating too much to make sure the corries get their fill, particularly with algae wafers. The b-n-s is 4 times bigger then a 'betta cup'(and its in the tank), but he still throws a hissy fit about it, spoiled brat. When I let him out he dashes right to the bottom looking for scraps as he's such a piggie. You can tell he's not bothered by the confinement, but being sequestered from FOOD! I've also had him take on food that was way too large and he would yack it back up.
