Original release notes

A big update for your tank.

· New mini-game, Shark Dodge: fish swim down the lane in a line. Swipe freshwater fish left and saltwater fish right, and never touch the shark! Earn a few coins every day, to retro chiptune music. Open it from More in your tank.
· Fry grow up: fish you hatch or breed start as tiny fry and grow into adults over a few days.
· Tank Journal: your tank keeps a diary of its special moments, with cards you can share.
· Live Activities: follow expedition and hatching countdowns on the Lock Screen and in the Dynamic Island.
· Shiny fish shine brighter, with a new golden glow and shimmer. Mutants no longer glow, so shinies stand out at a glance.
· Collection: see every mutant color you own.
· The pufferfish now puffs up when startled.
· Fixes and polish.
