Seahorse

''I caught a sea horse! Nay? Yay! - City Folk''

The seahorse is a type of fish found in the ocean at any time of the day, between the months of April and November. It has a tiny shadow size, the same size as the Clownfish and Surgeonfish. It sells for 1,100 Bells. In the "Bugs and Fish" window in City Folk, it says, "The female lays her eggs on the male. It's his responsibility from then on."

Donating to the Museum
Upon donating to the Museum, Blathers will say;

"This creature is covered in hard scales that suggest a relation to crabs or shrimp, but it's a proper fish. That said, it's a dreadful swimmer and can't usually move against powerful currents, eh wot? In such environments, the sea horse will cling to kelp and stay there until the waters calm a bit... Seeing those little fellows holding on for dear life makes me want to cheer them on! Cling, sea horse!"

It can be found in the bottom-right tank with the other small, ocean fish like the Clownfish and Sea Butterfly.

Further Information
There are many species of seahorse in existence, so judging by the coloration and look of the Animal Crossing seahorse, it could possibly be a Red Oceanic Sea Horse. The males carry the eggs in a brood poach located under the tail. It is a harmless, but popular aquarium fish.
