This is both a bug report and a suggestion - based on a glitch I've been seeing in my game recently... ...Skyfish! Recently, I've been seeing fish that "swim" up to 5 blocks or so out of the water. While this is clearly a bug, I think it'd be a great idea if there were intentionally skyfish - fish that swim around at certain altitudes in the air! (sorry I don't have any further information for a bug report - I didn't think to save my log before quitting and I don't know if or when I'll find the skyfish again. If I do see them, I'll try to submit a proper bug report, but for now, I just want to suggest it as an actual thing that should actually happen)
