Rhad - OBI OBI Creek 2.5cm

Rhad - Obi Obi Creek

Rhadinocentrus or Rhads are a stunning species in the rainbowfish family, they often get overshadowed by the Melanotania's and Pseudomogil's however these fish are just as beautiful. These Rhads are from Obi Obi Creek which is a fairly small geographic range that makes them a super unique fish. Adding these fish to a mixed rainbowfish display or preserving the species in captivity through a biotope aquarium would be stellar.

Obi Obi Creek Rhads have a look that is almost exclusive to the Rhadinocentrus family and not observed in any other fish. They have a very arrow-shaped body, and the pointed face with a thin, slender body really shows off the beauty of these fish. The body colour is a gradient of olive green from the back to creamy silver near the belly. Overlaid on this is a jet-black honeycomb patterning of scales which also transitions into spots. To contrast all of this, the most recognisable factor of these fish is the deep orange present on the top of the face which runs to the dorsal fins as well. As these fish swim and catch light the metallic scales reflect amazingly which adds a beautiful shimmer.

Breeding these Rhad rainbows in the home aquarium is possible as males tend to grow larger and show far more vibrant colours as well. Females also tend to have lighter black scale patterning with smaller fins as well. As juveniles, it can be hard to sex them however getting a group of 5-6 ensures a decent mix of males and females for breeding purposes. Once these fish reach maturity, they tend to breed on an almost daily basis and aquarists often use breeding mops to collect the eggs and rear them in a separate tank.

Tank Recommendations for your Rhad - Obi Obi Creek

As the Obi Obi Rhads fish do reach around 12 cm, but more importantly are active it is best to keep them in an aquarium with a minimum volume of 70 litres for a trio of one male and 2 females. For a larger school, it is best to go above 180 litres as this ensures that they can be kept in a school and have ample swimming space as well. The rhad rainbow is totally plant-safe and will not only love but also look great in a well-planted aquarium. They are mostly mid to top-water dwelling fish so the choice of substrate and aquarium hardscape is not a major concern. They are however excellent jumpers so a tight-fitting lid is a must for the aquarium. Rhads are also a tropical fish which are best kept at 24-26 degrees.

The Rhad is incredibly peaceful but due to their speed, they may potentially outcompete slow or bottom-dwelling tank mates. They can however be kept in a wide range of community aquarium settings and with other rainbow fish strains.
