Seahorses are amazing little (some as small as 1") animals which can actually do quite well in an aquarium. This terrific (12" X 12" X 20" high) DIY 12g Seahorse Tank costs less than $30 for the glass and takes less than an hour to build. You can build a Seahorse Tank any size that you wish, by simply adjusting the dimensions of the tank and following the easy-to-follow instructions. The photos in the Top Seahorse Photo Gallery show you some of the Seahorses you raise in your new tank.

You can even put a mated pair of Seahorses in one of these tanks and see what it is like to breed and raise your own.
