Maintenance Requirements

regular maintenance is essential

To ensure the proper care and maintenance of Brochis multiradiatus, it is essential to create an environment that replicates their natural riverine habitat. Water parameters play a crucial role in maintaining their health and well-being.

The tank setup should include well-oxygenated and well-filtered water with a current, mimicking the natural flow of rivers. It is recommended to have a tank depth of at least 18 inches to replicate their preferred environment. Additionally, a soft, sandy substrate should be provided to protect their delicate barbels.

Brochis multiradiatus thrive in heavily planted tanks with ample hiding spaces, such as driftwood and rocky structures. As social fish, they should be kept in schools of 3 to 6 or more.


Brochis multiradiatus exhibits a diverse diet consisting of prepared foods, live or frozen bloodworms, tubifex, and daphnia, making their feeding requirements crucial for their overall health and well-being. These fish are voracious eaters and require a variety of foods to thrive. Providing a balanced diet is essential for their optimal health.

To give you a better understanding of the feeding requirements of Brochis multiradiatus, here is a table that highlights the different types of food they consume:

Food Type Description
Prepared Foods Algae tablets and sinking pellets are readily consumed by Brochis multiradiatus.

selective breeding for specific traits

The breeding process of Brochis multiradiatus, a relatively rare schooling fish with deep colors, elegant fins, and an elongated snout, is challenging to achieve in captivity.

Breeding challenges arise due to the species' specific spawning behavior. Brochis multiradiatus engages in substrate spawning, with females carrying eggs in their pelvic fin basket. The eggs are then adhered to suitable surfaces, such as the undersides of floating plants. The difficulty lies in replicating these conditions within a captive environment.

Additionally, sexual dimorphism between males and females makes it crucial to identify and pair compatible individuals.

Despite these challenges, successful breeding can be accomplished by providing suitable spawning surfaces, maintaining optimal water conditions, and offering a varied and nutritious diet.
