Adult brine shrimp are probably one of the most common foods recommended by local fish shops to feed a seahorse. However they are very low in nutritional value and should be enriched with vitamins before feeding them to seahorses. A seahorse will happily eat brine shrimp but will die if no other nutritional foods are fed to them.
Copepods are very small crustaceans that can be found in plankton. In an established aquarium with live rock there will be plenty of different species available. They can often be seen on the glass before you turn the tanks lights on. They are a good food source for fry but hard to maintain in large numbers
This food source is readily found in rock pools so if you live by the sea then they will be a eagerly eaten by your seahorses. They are up to 2.5cm long and change colour depending on what algae they eat.
Mysis shrimp are a great food to feed seahorses. They are about 2.5cm long and an adult seahorse will happily consume 30 of these per day. They are not readily available in a fish stores and certainly live ones are very hard to come by.
Rotifers are very good when helping to raise seahorses. They are very small and available from most fish stores. It is always a good idea to enrich these before giving them to seahorses.

These are a good food source for seahorses but hard to find in the wild. They are found under rocks in rock pools.
