Dwarf seahorses are a joy to watch. We watch these little guys more than anything elses around here.
They require a small, species only aquarium. Please do not put these in your reef tank! A 1 to 5 gallon aquarium is best, the smaller aquarium size helps concentrate the food. The aquarium should have an air stone or sponge filter for water movement (no powerheads, they will suck up the horses!) and a heater. Walmart has some great neat cheap small tanks that work great for them. They dont need anything fancy.
Dwarf seahorses require a continuous diet of freshly hatched baby brine shrimp. We feed ours daily. They can be housed with Dwarf pipefish, snails and thats about it. Anything else generally out compete them for food. They like to grasp Caulerpa and other items with their tail. Live rock and live sand may contain stinging animals that can be aggressive towards them. We reccomend using fake plants and keeping the bottom bare. We use coffee straws glued to frag disks for them to hold on to. A small water change every few days will help keep the water clean.
Dwarf seahorses will breed in the aquarium. The mating ritual is fascinating to observe and they mate often. The male will show off for its mate and blow up its pouch, shake and dance, and change different colors. When the eggs are ripe, the female will deposit her eggs inside the male pouch as they travel up the water column together. In about 10-14 days, the male will give birth to an average of 10-30 fry, which are independent from birth and will eat baby brine shrimp. The babies are well developed and use their prehensile tails almost immediately, growing very fast when provided with plenty of newly hatched brine shrimp each day, and will double in size in just 17 days, and after 3 months, will be ready to mate.
Dwarf seahorses are small and only grow to about 1 1/2"
