Dwarf Seahorse

From ReefPedia

Dwarf seahorses or hippocampus zosterae, is one of the most popular aquarium seahorses. You may keep as many as 4 in a 2 gallon tank and as many as 20 in a 5 gallon tank, which is the normal tank size. These fish are not very colorful like other seahorses, but some have nice light pastel colors and unusual patterns. These are incredibly tiny fish no more than an inch and a half, tail included. They must be fed baby brine shrimp twice a day and there must be enough shrimp to give the tank a snowy look. These fish are highly prolific breeds, and will breed rapidly between Febuary and October. The fry can live in the main tank with the parents and will eat newly hatched artemia naupli.
