Recently I've noticed that when a family member says they're going to "feed the fish" in the aquarium, they stop in the middle of getting the food and go do something else. They've also completely stopped "bothering the fish" and looking at the Magic Fish. Time for a new aquarium?

Hi Grumpity. The fish don't die. Not knowing where your aquarium is placed, try moving it to a new location.

probably some furniture is blocking yhe way for your people to the fish tank.

You know, that's exactly what I did. Then I dropped someone onto the tank, they said they were going to feed the fish, but they stopped again after going to fetch the food. So I moved it back to where it was originally. They still don't succeed in feeding the fish, but now this family and all the others with aquariums have gone back to looking at, bothering, and admiring the fish. Funny, that. Thanks for the replies!
