Dwarf seahorses do well in a small aquarium but have few compatible tank mates. Ocean Rider sells farm-raised dwarves (they call them Pixies) and list these facts about them:
Size: 1 - 1 1/2 inches
Color: Ranges typically from mottled brown to white, sometimes yellow, green or black and less commonly multi colored--yellow and black, polka dotted and pinto.
Life span: Wild approximately 1 year, captive 2-3 years plus.
Feed: Artemia, all stages, preferable newly hatched nauplii. Also various shrimp larvae such as Gammarus, Mysids, red shrimps and ghosts.
Feeding Frequency: Two times a day.
Behavior: Promiscuous, prolific. Like to hitch and feed on bypassing live food. Short wait list of 2 weeks. You will be protected from any price increases during the waiting period and you will recieve a free Pixie treat with this purhase and any future pixie purchases. You choose the treat....live baby brine shrimp, baby brine cysts, Hawaiian Ogo (great hitchin post and copepod habitat!)
Offspring: Average amount of fry from 3-30, most common around 20.
Fry: Approximately inch, benthic, able to hitch right away.
Natural habitat: Florida to the Bahamas. In the wild they often have parasites.

Tank mates: Very few are compatible. Tiny hermits, red shrimps, sea bunnies and snails.
