Here is vintage ceramic tile from Spain produced by ONDA decorated with vivid colors of a brillant Moorish Idol or a similar tropical reef fish.  It is depicted in side view in vibrant yellow and black with green accents. 

The square tile measures 6 x 6 inches with 1/4 inch thickness.  It comes held in a frame of thin yet stout metal that was once covered in black paint that's now gone. There's a wire loop on the back frame for wall hanging. It weighs 12.5 ounces

This small ceramic work of art was likely crafted in the 1950s, and is a great piece for lovers of tropical fish who appreciate vintage decor.

Condition is a bit rough but no scratches and is still in decent shape.  The upper corners have a chip that's mostly conceal by the metal frame.  The tile back is soiled and has a chip, see last photo.  None of these issue detract from its beauty, but price has been reduced accordingly.

Thanks for looking.
