Seahorses seem to greatly prefer a tall tank rather than the "normal" short rectangular aquariums that you see on the market. Not being aggressive feeders, they also prefer an environment with little competition for food and not a lot of current. Not seeing anything on the market that fit these parameters, we decided to design and build our own Seahorse tank.
We started with the dimensions of a standard 10g tank (10" X 12" X 20"), turned it on its end and expanded it to 12" X 12" X 20", making it a tall 12g tank. This size seemed perfect for holding a power filter, heater and the 12" Coralife PC Aqualight.
