# Growing up

_How a fish grows from hatchling to adult, and how long it takes._

## From baby to adult

After hatching, a fish is a baby for the first quarter of its growth time, then a junior, and finally an adult once its full growth time has passed. You can watch it get bigger along the way.

## Growth times

Each species grows at its own pace, from 3 minutes for a Goby to 1 week for a Grouper. The [species catalogue](https://fishies.lol/wiki/species) lists every one and can sort by growth time.

Growth follows the server's clock, so a fish keeps growing while you're away.

## What changes the pace

A hungry fish stops growing until it's fed again. Cloudy [water](https://fishies.lol/wiki/mechanics/water) slows growth too: below 70% water a fish grows more slowly, down to 60% of its normal speed at the very worst. Neither ever undoes growth that has already happened.

## Once it's grown

Only adults can be [sold](https://fishies.lol/wiki/mechanics/economy). There's no rush: an adult is happy to keep swimming until you decide, as long as it's still fed.
