A law passed in England makes is illegal to mistreat a goldfish. What kind of nonsense is this? It's the kind where people care about so-called 'animal rights' more than humans.
Goldfish are notoriously easy to mistreat. Especially since they are a low-emotional attachment first pet to introduce children to the idea of responsibility. The natural consequences are blatant. What a loss for the learning process of every human when goldfish are expensive to buy (heated water?) and cost a ton of money (up to 20,000 pound fine) when they are killed. Guess you won't be going away for the weekend without taking Goldie to the goldfish kennel.
