Real talk: putting almost any lifeform in to too-small an enclosure, with too few elements from their natural environs, is a pretty effective way to make their lives more miserable and get the least-interesting experience out of appreciating them.

I had a goldfish for 17 years, it was a great comfort of times of turbulence and hardship.

I’ve never bought fish or cage-pets because I’ve always seen it morally wrong - buying living thing, imprisoning it in a small enclosure for your own entertainment. Then my sister got me a hamster for birthday. I constantly felt bad for the thing and wanted to set it free, but also didn’t want to hurt my sister since she occasionally came to visit. Lived to the best of my comfort-assisted abilities for 3 years till death.
