You're all cowards for only posting mammal pets. Here's my fish. They are 14 years old, 4 years beyond their expected lifespan and older than many Osirans. They spent about 5 to 8 of these years without food, filtration, water changes or sunlight (to my chagrin, I moved them to a clean aquarium and have been feeding them for like 3 years-ish) without encountering any clear health issues whatsoever. They are now in a proper tank and being cared for properly but I'm unable to add more fish to the tank because they take up so much space. It's been so long that i have no recollection of their original name
Don't get weather loaches kids, they're indestructible and they scare me
