When Kenza was in Kindergarten, we bought her a ten-gallon aquarium and five black tetra fish. I expected them to live maybe a few months – but here it is six years later and we still have three of those black tetras. They’ve survived everything from small kids petting them to a leaking aquarium while we were on vacation, leaving them with only a small amount of water to swim in. Sideways.

Recently, this one has grown a weirdo tumor, and I totally keep expecting him to join hamster #3 in the freezer any day now, but, remarkably, this little piece of sushi keeps on swimming.
