Is it best not to keep fish as pets?
I was thinking of getting an aquarium tank recently, just because it's possible to make them very beautiful. I was planning to do it without fish, but I do think fish are very cute. It seems like it's debatable exactly what fish do/don't feel compared to mammals like cats, dogs, pigs, horses etc. But I don't like the idea of keeping them if they're sentient enough to be aware they are stuck in a small space.
