The Pajama Cardinal is one of the most popular marine aquarium fish, not to be confused with the similar but less-attractive Orbic Cardinal (Sphaeramia orbicularis).
Like other Cardinals they are mouth brooders however the larvae do not develop in the mouth. They are released upon hatch and are among the most challenging larvae we work with. Most hobbyists assume that all Cardinals reproduce just like a Banggai Cardinal and often overlook the significance of the availability of other species.
As with most cardinals, they are generally docile in aquariums and should not be housed with overly aggressive tankmates.
They are a great fish for reef tanks, and swim freely in full view. They will eat a variety of aquarium foods including frozen foods and pellets.
How We House Our Fish
All of our fish are housed in dedicated captive bred fish systems. Each of these systems is dedicated to a single breeder and used to house the captive bred fish we receive from them. Great care is taken to ensure these systems do not get cross contaminated. We only introduce new fish into these systems when receiving an order from that system's breeder.
We do this as it allows us to ensure our fish are pest free without the need for medications. However, should any pest turn up we can and will medicate these systems.
Medicating fish is hard on them and diminishes their overall health. While medicating is a good precaution to take with all wild fish, captive bred fish from a trusted breeder can forgo medications and ultimately will be much healthier because of it.
That being said, when exposed to a tank where pests are already present, likely from an unmedicated wild fish being in the tank, these captive bred fish are by no means immune and can be infected. So it's important that all wild fish introduced to your system go through a proper quarantine.
Observation and Inspection
Upon arrival all of our fish go through an observation period of one to two weeks, depending on how long their journey to our facility was. During the observation period, the fish are inspected to ensure they are eating, aren't showing any visible signs of stress or pests, and otherwise look healthy. If they pass our inspection, they will be made available on our website.
