Aquarium Conditioned-Cortez Blacknosed Barber Butterflyfish

Aquarium Conditioned-Cortez Blacknosed Barber, Johnrandallia nigrirostris.

Size: ~3-3.5 inches. They will reach up to ~4-7+ inches with maturity.

Please see unique care information for this species below:
Cortez Barber Butterflyfish are a unique butterflyfish species. This species native to East Pacific, Mexco, Peru, and Galapagos islands. In their natural environment they are often seen in pairs. We are feeding them a variety of prepared foods including frozen Mysis shrimp, LRS frozen nano blend, TDO XS pellets and a variety of other prepared foods at our farm. We recommend feeding them often such as 2-3+ times daily. They love PE Mysis shrimp.

We recommend housing this species singly or paired. These do really well paired. There is a possibility of them nipping at corals, anemones, scallops and clams, especially when underfed. Keeping them well fed tends to reduce this risk and they are often fine with corals in the aquarium. Of course, keep an eye on them. These are also great in larger aquariums with all artificial hitching posts or FOWLR aquariums. We recommend a 75 gallon or larger aquarium size for this species. They like swimming space and having lots of branch rockwork.

These fish have a lot of personality and can make for a fun and unique tank mates in your seahorse aquarium, FOWLR aquarium and even some mixed reef tanks. There is a possibility of them nipping at some coral species but this is pretty unlikely in our experience. Many of these species like to explore the aquarium with their mouth and they may take an occasional nip at a coral but this is unlikely to be harmful to corals in many instances.

Our Aquarium Conditioned fish are quarantined and observed at our aquaculture facility before offered for sale. We prophylactically deworm all our fish as well as run an anti-parasitic treatment on all of our fish.
