Who we are
Hand-Raised Beauty, Born from a Love of Colour and Care.
Rudy’s Aquarium is a small, family-run setup born from Mr B’s lifelong love of tropical fish, inspired by his roots in Belize — where vibrant colours, natural beauty, and aquatic life were part of everyday magic.
An automotive mechanic by trade, Mr B brings the same precision, patience, and dedication to breeding beautiful, healthy Betta fish at home in South London. With the creative support of his artist wife (and occasional input from their young son Rudy, the brand's namesake), this is truly a passion project turned small business.
We focus on ethical, small-batch breeding of Betta splendens — ensuring zero-stress travel, healthy genetics, and vibrant colours.
While Bettas are our specialty, we’ll soon be introducing other beautiful species to our collection.
We believe fishkeeping should be joyful, mindful, and accessible — whether you're a beginner or a collector.
