RJ AQUA is a full-service aquarium, aquatic livestock, aquascaping, and water feature company serving Los Angeles and Southern California. We provide complete solutions for aquarium hobbyists, collectors, businesses, retailers, and commercial clients—from livestock and aquarium supplies to custom installations, ongoing maintenance, ponds, and outdoor water features.

Our livestock division offers a growing selection of freshwater aquarium fish, ornamental fish, turtles, koi, and specialty aquatic livestock. We serve both retail customers and wholesale partners, with a focus on healthy livestock, responsible handling, professional packing, and dependable supply. Our selection includes L-number plecos, datnoids, tinfoil barbs, koi, and other distinctive freshwater species, with additional livestock categories continuing to expand.

Beyond livestock, RJ AQUA provides aquarium equipment, filtration, accessories, aquascaping materials, décor, and related aquarium supplies for both individual customers and professional projects.

Our custom aquarium and aquascaping services cover the complete process, including aquarium planning, system design, tank selection, filtration, installation, aquascaping, setup, and long-term care. We work with residential, commercial, and specialty environments to create aquarium systems that balance appearance, animal health, reliability, and ease of maintenance.

We also provide professional aquarium cleaning and maintenance services, including routine cleaning, water changes, filtration service, system inspections, water quality management, livestock care support, and ongoing aquarium maintenance.

For outdoor aquatic environments, RJ AQUA offers solutions for koi ponds, garden ponds, decorative water features, and aquatic landscape projects, including planning, setup, filtration, maintenance, and related services.

Our wholesale division supports aquarium stores, dealers, resellers, and other industry partners with livestock, aquarium products, and supply solutions. As our operation grows, we aim to provide dependable sourcing and long-term support for both retail and wholesale customers.

From a single aquarium to a complete commercial system, from freshwater livestock to koi ponds and outdoor water features, RJ AQUA provides integrated aquatic solutions from tank to pond.
