Fostering fish?

So, they have foster homes for cats and dogs. Do people foster fish? Mr. Raisins and I are the lazy owners of two fish tanks, one is 80 gallons. We love the fish and how they're still alive is a mystery to us. If anyone ever tells you it's hard to keep fish alive, they're lying. Anyways, we won't be able to take the fish with us for the big move to Cali in a year. I don't like the idea of just flushing the guys. Especially the big, ugly goldfish who is now white and ugly from a case of fin rot. He's been hanging in there for over 2 years. Hence, the question of whether people foster fish. Plus, we have a special needs fish in the small tank who lives with a guppy. The guppy spends his time up high while the handicapped fish lives in the castle, only coming out to eat. We don't know what happened to him, but his back half appears to be paralyzed, so he's much smaller than his brother because of atrophy and he's kind of S-shaped. And he apparently is only capable of swimming in a vertical position. He's my favorite. My own little Nemo.

If anyone will have a desire for an 80-gallon tank with 2 rainbow sharks, 2 albino sharks, three tetras, 1 goldfish, 2 suckerfish, 1 African bumblebee, 1 yellow lab, some cool blue-striped fish, and some big, expensive, ugly fish (like I know everything that lives in there) we may have something for you next year.
