# Room in your aquarium

_How many fish and decorations fit, and how that grows._

## Fish

Your aquarium starts with room for 8 fish and grows to 24 as you level up, with the first extra space at level 4. Eggs take up space too, and so does a lost fish until you collect it. From level 25, [more aquariums](https://fishies.lol/wiki/mechanics/aquariums) add the same room again.

## Plants & decorations

The floor holds 30 plants and decorations to begin with and up to 40 later, with the first extra space at level 21.

## One to an aquarium

A few fish are limited to one per aquarium: each [legendary fish](https://fishies.lol/wiki/mechanics/legendary) and the [Bristlenose Pleco](https://fishies.lol/wiki/species/bristlenose-pleco). Once one is in the water, that aquarium can't take a second.

## When it's full

Sell a grown fish with the [Net](https://fishies.lol/wiki/mechanics/net) to free a fish space, or sell a decoration to clear the floor. The shop always shows how full you are and the level of your next increase.
