Fish game I can't remember the name of (someone help!)

Ah, sorry, hit post accidentally. So it was this side-scrolling game where you play as a fish swimming through the ocean. There was a single control mechanic of tapping and holding the screen to make the fish descend into the water and then when you release, it ascends back up to the surface (think Jetpack Joyride, but instead of holding to go up, you hold to go down). Similar to Jetpack Joyride, the aim was to avoid obstacles, and it was extremely addictive. There were multiple levels with different backgrounds and obstacles (I think one was called "Champagne waters" or something along those lines? Really scratching my brain here for stuff I remember) I remember playing it somewhere between 2010 and 2013, though can't remember when exactly, and I have no way of knowing whether it still exists on the app store. Does anyone remember this game?!
