</>What does Growth Spurt do?
Waiting for fish to grow up is the longest part of Chillquarium — some take real-world hours. Growth Spurt makes every feeding count for far more, so a single meal can take a fish from baby to full-grown adult. Prefer instant results? Hit the Grow All button and every fish in your current tank matures on the spot, ready to earn income and join your collection. It's ideal for filling out sets fast or getting a new tank producing straight away. Turn the feeding boost off whenever you want fish to grow at their own gentle pace again.

</>Common questions about Growth Spurt
What does Growth Spurt do in Chillquarium?
Growth Spurt speeds up how fast your fish grow up in Chillquarium, which is normally the slowest part of the game. It works in two ways. First, it supercharges feeding, so a single meal pushes a fish far further toward adulthood — often taking it from baby to full-grown in one feed. Second, it adds a Grow All Now button that instantly matures every fish in your current tank on the spot. Adult fish earn income and count toward your collection, so growing them quickly gets a tank productive right away. Growth Spurt is a free-tier mod from ProjectMods, the community-first PC mod manager, and you can switch the feeding boost off whenever you want fish to grow at their normal pace.
What's the difference between Feed Power and Grow All Now?
Growth Spurt gives you two separate ways to mature fish in Chillquarium. Feed Power is a slider that controls how much each feed grows a fish — set it higher and a single meal does far more growing, so fish reach adulthood in fewer feeds while still growing through the normal feeding action. Grow All Now is an instant button: press it and every fish in your current tank jumps straight to adult, no feeding required. Feed Power suits players who like the rhythm of feeding but want it to go faster, while Grow All Now is for when you just want a tank full of grown fish immediately. You can use either one, or both together.
How high can I set the Feed Power slider?
The Feed Power slider in Growth Spurt decides how much a single feed grows a fish in Chillquarium, and you can push it high enough that one meal takes a baby fish all the way to full-grown. Lower settings give a gentler boost that still cuts down the wait, while higher settings collapse the whole growth process into just a feed or two. This lets you tune the pace to your taste: a mild speed-up if you still enjoy watching fish develop, or a dramatic one if you want results almost immediately. Whatever you choose only applies while the mod is enabled, so turning Growth Spurt off returns feeding to its normal, slower effect.
Does Grow All Now affect every tank or just the current one?
Grow All Now matures every fish in your current tank in Chillquarium — the one you're viewing when you press it — rather than every tank at once. If you keep several tanks, you can grow them one at a time: open a tank, press Grow All Now, then move to the next and repeat. This gives you control over which tanks you fast-track, which is handy if you want to bring a new tank up to speed while leaving others alone. Every fish in that tank jumps straight to adult, ready to earn income and count toward your collection. For growing fish across many tanks quickly, it pairs well with the Feed Power boost.
Why would I want to grow my fish faster in Chillquarium?
Growing fish faster in Chillquarium mainly means reaching the good parts sooner. Only adult fish earn passive income and fully count toward your collection, yet by default some take real-world hours to mature — so a new tank can sit unproductive for a long time. Growth Spurt removes that wait: fast-track a fresh tank so it starts earning right away, finish off a set the moment you've collected the fish, or turn a batch of new pulls into grown, income-earning fish instantly. It's especially satisfying alongside pack-opening mods, since fish you gain in bulk can be grown up on the spot instead of one slow feed at a time. When you'd rather savour the slow pace again, just switch the boost off.
