Here's a fish that changes it's stripes over time! The oriental sweetflip starts out as being a fully striped fish. However, as it ages, it trades in some of its stripes for spots instead! It tail, along with some of its fins, go from being striped along with the rest of its body, to sporting an abundance of thick, non-uniform black blotches on a contrastingly yellow backdrop, that forms a striking spot-like pattern.
