Free ceramic fish dish

What a cute little thing this is.... somebody was silly enough to throw it out!  My niece Rebecca grabbed it along with some other nice ceramic things, but she was kind enough to pass this one onto me straight away.

I'm not sure what it's used for,  but I popped in a couple of cotton balls drenched in essential oils (lavender, vanilla, mmm!!!) and I'm also thinking I can put a little tea light in and the light would prettily shine through the holes.  Adorable.
