Some of these fish will outlive your skincare routine while others barely make it past a Spotify free trial.

Most people think fish are low effort, low drama, and low lifespan. But aquarium life has its own chaotic curveballs, and not every fish is built for the long haul. Some of them are practically eternal roommates who see multiple generations of pets come and go. Others? They flake faster than a bad date. If you’re getting into fishkeeping thinking all of them will chill for years, you might be setting yourself up for heartbreak, or worse, expensive tank resets.
Some fish are basically swimming investment pieces. Others are moodboard creatures that disappear before you even finish naming them. This list spills both types, because if you’re gonna spend time feeding something every day, you at least deserve to know which ones ghost and which ones stay.
