Ostorhinchus sealei

The Seale’s Cardinalfish is a fairly new addition to Biota. Most aquarists may not recognize these fish because they've always been so scarce in the aquarium trade. Finally, Biota's captive breeding efforts have made them available.

Juveniles have a yellow accented silver body with blue eyes and contrasting black stripes. Their real beauty shines as they age and they develop a bright lemon yellow coloration, and their stripes take on a warm pinkish hue. The blue eyes and accents on the face become more pronounced and reflective.

Unlike so many reef aquarium fish that are aggressive toward conspecifics, these fish do great in shoals. The ideal tank size for a trio is 30 gallons or larger, though bigger shoals can be kept in larger tanks. It may seem counterintuitive, but offering plenty of safe hiding places encourages these outgoing fish to spend their time in the water column where they are nearly always visible to observers. Their very peaceful nature puts them at risk of bullying from more aggressive species, so they do best with only other peaceful fish.

Acclimation

Temperature Match

Place the sealed bag containing the fish or invertebrate into your tank. Allow it to float for 15-20 minutes to gradually equalize the temperature between the bag and your aquarium. This step minimizes stress caused by sudden temperature changes.

Drip Acclimation

Set up a drip acclimation system by using airline tubing. Start a slow siphon from your tank into the bag or bucket containing the fish or invertebrate, allowing water to drip slowly. Acclimate over a period of approximately 30 minutes, gradually increasing the volume of tank water to match salinity and other water parameters.

Check Salinity

Use a refractometer to measure the salinity in the bag or acclimation container. Ensure the salinity matches your tank’s salinity before transferring the fish or invertebrate. Matching salinity helps reduce stress and prevents shock when introducing new animals.

Release Fish/Invert

Gently transfer the fish or invertebrate into the tank, avoiding netting them if possible to reduce physical stress. Allow the animal to swim out on its own if transferring from a container. Discard the acclimation water, as it may contain contaminants.
