Bluefin Notho - Nothobranchius rachovii : Complete Fish Profile & Care Guide
Table of contents
Introduction
The Bluefin Notho is a fascinating and strikingly beautiful species of killifish that brings a pop of colour and lively activity to any aquarium. However, to ensure their optimal well-being, this species is best kept in a specialized community. For those who wish to keep more than one male in the same tank, a spacious and heavily decorated aquarium is a must. This will allow rival males to retreat to safety if necessary. Alternatively, a species-only breeding tank with 2 or more females per male is recommended. If tankmates are desired, it is best to keep the Bluefin Notho with other species that enjoy the same softwater conditions, such as Pencilfish, Kuhli Loaches, Corydoras Catfish and Gouramis. However, this species is not suitable for a general community tank. To create an ideal habitat for the Bluefin Notho, it is crucial to have a heavily planted aquarium that includes floating species and plenty of bogwood. Incorporating Catappa leaves into the aquarium can provide numerous benefits for the fish and the overall aquatic environment. The leaves are known for their natural antibacterial and antifungal properties, and they can also help to lower the pH level and soften the water. Furthermore, the leaves release tannins that can give the water a beautiful brownish hue, providing a natural and attractive setting for the fish to display their vibrant colors. Filtration should be efficient but with gentle water movement, and small partial water changes should be carried out regularly. Finally, tight fitting coverslides are a must to prevent this species from jumping out of the tank. The Bluefin Notho is a small, brightly coloured fish that will add a splash of vibrancy to any aquarium. Their scales have a unique iridescence that can shift between deep blues and brighter blues, depending on the angle and lighting. Their fins are also colourful, displaying the same body colouration with contrasting red edging that appears like bands along their body. The females, on the other hand, have a drabber appearance with a dull brownish-yellow colouration and clear fins. Overall, these fish are a true delight to observe in the aquarium.Bluefin Notho Photos
