This small saltwater fish 4-30cm (1.5 12in) long looks like a tiny hobby horse. It has a prehensile tail (it can grasp things) and it swims upright.
A seahorse tank should be at least 18 inches tall. Seahorses prefer to move up and down in an aquarium more than side to side. If you are going to keep more than one small seahorse or one of the larger seahorse species, you will want a larger tank.
Because they are not strong swimmers (and because their gills are not very efficient), seahorses do not like strong water movement.1? Seahorses have a short and very primitive digestion tract, which allows a great deal of undigested food to end up on the bottom of the tank, adding to water quality issues.
Seahorses need at least one hold fast or hitching post in the tank, so they don’t have to be constantly swimming. If they aren’t looking for food, seahorses will spend most of their time with their tails wrapped around almost anything that will hold them in place. Gorgonians work great for hitching posts, as do faux corals or even plastic aquarium plants.
