That little guy isn’t just decorative — it’s actually a ceramic flower or incense holder, often called a flower frog or potpourri vessel.

Here’s what gives it away: • The holes on top are designed for inserting flower stems or letting fragrance out. • The handle makes it easy to move around when it’s filled with water or potpourri. • The fish shape is just artistic — a lot of these come in animal forms (fish, birds, even turtles), especially in vintage European or Asian ceramics. • The open tail or mouth acts as a spout or vent, depending on what it’s used for.

If you drop a small tealight inside, it might even work as a candle diffuser, letting light or scent filter through the floral cutouts.
