"Swim along with the snorks"
your best chance was when the tail was visible, and even if you could reach it with a toothpick tweezers might have worked. Now though I don't know. If you have any other otos in there I'd move them out. Don't you have like 6 goldfish in there? I think it was only a matter of time before they tried it, goldfish are hungry hippos. Sorry to hear
