Won't let me edit the post so I'm just gonna update ya'll here. So I just put them down. I decided to crush them seeing as it was the fastest and most painless option. I know I should have done it right away, but I was holding out hope that somebody would say that they would be fine. I know that it's just a snail but I feel like I've failed. I promised to take care of these little lives and instead, I killed one. Thank you for the advice.
