I've had (attempted) rescues die, and I've just sent, for the first time, a semi-rescue in the mail, but tomorrow I'm going to be giving away one of my fish to a place that I don't have direct control over and where I can't be 100% sure of his care. I know that probably sounds awful, but I have a quadriplegic step-sister who loves pets. I put a big yellow & blue multi-colored VT in her room when she was staying here one weekend, and she asked to keep it. He's not one of my absolute favorites, and I don't have any real emotional attachment to him, but it's weird to be giving one away where I won't get reliable updates on him (due to complicated family stuff).
Now, I do know that he will be taken care of, because that whole family loves pets--he'll probably get better care than most people buying bettas in pet stores give, so that's something. I'm giving them a tank along with the fish, and am currently going back and forth between a medium kritter keeper with one of my spare heaters, or a 1-gallon tank with lighting and an under gravel filter. So I know he'll have something decent, either way, plus my little sister will have one less tank to clean while I'm on vacation. It's just weird to be saying good-bye to the boy that blows me a bubble nest that completely covers the top of his tank every time I change his water. *sniffle*
