Hikari, manufacturer of tropical, marine, pond and coldwater fish foods, is searching for the wittiest fishkeepers to submit their captions for its latest competition.
Our technical writer Nathan Hill got up close and personal with the brand at the recent AQUA Telford show, and is subsequently still "full of spirulina".
The top 20 entries will bag themselves an 82g pack of Hikari Algae Wafers, which provide a complete and balanced diet for Plecostomus and other algae eaters, including marine herbivores.
For your chance to win simply click here to send Hikari a caption that best describes what you think the image is saying or thinking, or just a general description.
Maximum number of words is 15.
Closing date for entries is Friday December 6 2013. All winning captions will be uploaded to the Hikari website after the closing date.
