Fluorescent ornaments do a specific job that a plain rock can't: under the right lighting, they're the part of the tank that actually stands out.

This is a polyresin ornament, hand-made and hand-painted with non-toxic paints, sold as one of four designs - a Mermaid, a Fairytale Castle, a No Swimming sign and a Sculpted Rock.

• Polyresin construction
• Hand-made and hand-painted with non-toxic paints
• One of four designs: Mermaid, Fairytale Castle, No Swimming or Sculpted Rock
• Overall average size approximately 115mm long x 35mm wide x 115mm high
• Described as one of the range's best-selling styles

On the design: because this is an assorted listing across four different designs, you can't specify which one you'll receive - a Mermaid and a No Swimming sign look nothing alike, so it's worth being comfortable with any of the four before ordering.

Who it's for: aquarists who want a bright, characterful ornament for a younger fishkeeper's tank or a fun-scenery setup rather than a natural-looking aquascape.
