The Pajama Cardinal, Sphaeramia nematoptera, also known as the Polka Dot Cardinal or Spotted Cardinal, has an incredibly unique color and pattern on its entire body. Featuring a greenish yellow front half, divided by a black band in the middle of their body, followed by a spotted or polka dot dorsal region that is an off-white color with vibrant red-orange spots. At this price, this is one of the most colorful fish you can get in the aquarium trade.
The Pajama Cardinal is a slower swimmer, and extremely peaceful in nature, and should be housed with other reef safe, and peaceful tank mates. Because of their timid nature, they are a great choice to house with Seahorses and Pipefish. They can grow to be about 3.5" fully mature, and should be kept in a tank with plenty of live rock or plants to offer hiding places during the day. The Pajama Cardinal has a nocturnal living habit and will be most active during the night.
Since the Pajama Cardinal is very social, they do best in small groups or schools, in an appropriate sized tank of no less than 30 gallons for the school, and can be kept in a tank of 20 gallons individually. Larger tanks could allow for larger schools, and like many other schooling fish, the Pajama Cardinal will form a strict hierarchy when kept in small groups within the aquarium. Although some species do use aggression to exert dominance, this member of the family Apogonidae does not. They are an excellent choice for beginner aquarists as they are active, friendly, easy to care for, and easily adapt to captive feeding.
Pajama Cardinals are carnivorous, and should be fed a diet of vitamin enriched Brine or Mysis shrimp, along with other finely chopped meaty preparations. If you are finding the Cardinalfish is having difficulties eating, it can be best to feed the Pajama Cardinal at night. They will thrive in a temperature range of 72-78°F and a pH of 8.1-8.4.
These two guys have become the guardians of my mini rank. Hovering over their tank mates and making quick bursts whenever they have somewhere to go. Really cool colors and they fed soon after introduction into the community. Mysis shrimp and varied flakes are consumed . They like to stay up at night and roam. Very peaceful little buddies.

I have 3 of these I bought here and had shipped to MN this November. The arrived on a 21 degree day but after slow drip acclimation made it and swim lazily around my 40gal Reef Tank. They are a colorful addition to my tank and interesting to watch. I did not know before but do now that they are night foragers, so I will have to start dropping some pellets in at night. They do well when I feed the tank twice a day with Mysis Shrimp.

The fish was shipped extremely well, and it was a perfect addition to my reef tank. I acclimated according to the instructions, and I have had no problems with any of the fish I have received. What more can you ask for? Cheaper then my local fish store and it was delivered to my front door the next day.

Great little fish. Arrived in amazing condition. Once acclimated were quick to swim around and had them eating by the next day. Hardy fish with beautiful coloring and great personalities. One of my favorite.

Not a very bright colored fish but love how mellow he is. He just likes to watch what everyone's doing. Can't beat the price.
