Welcome to Colombo our mission is to develop and produce premium products, with a primary emphasis on water quality and animal health in aquariums, ponds and terrariums.

40 years of experience,
that makes the difference.

The start of your unique aquarium, pond or terrarium is here.
Colombo makes products which help consumers make their hobby of keeping ornamental fish and Reptiles a success! We make products for ornamental ponds, from the smallest goldfish pond to the biggest Japanese koi pond, for freshwater aquaria, from a small Betta tank to the biggest Discus tank and for marine aquaria, from a simple fish-only tank to a highly specialized reef tank. New in our range are products for Reptiles.

Medication & healthcare.
As Colombo was founded by veterinarian Dr. Mario Blom, medicines are at the core of Colombo. Many of the medicines developed by Dr. Blom himself are still among the top in the field at this moment. Colombo keeps investing in the development of new medications like Morenicol Lernex-Pro. All the Colombo medications are produced under the GMP standard which ensures that our medicines always meet your highest demands.

We develop in
our own laboratory.

Product development.
Every product we sell is developed in our own laboratory and is tested over and over for safety and efficiency, a practice spanning over 40 years! As part of the Aquatic Wholesale Group, we collaborate with sister companies to harness their expertise: Aquafarm and Ornafish contribute to fish and fish disease research, Aquafleur focuses on water plants and growth, and Aquadistri specializes in aquarium, pond, reptile and technical aspects. This collective effort drives ongoing product enhancement and supports consumers in maintaining healthy and beautiful fish, animals and plants.

Our mission.
Colombo’s mission is to provide premium hobbyist products, with a primary emphasis on water quality and animal health. We’ve developed a comprehensive range of test kits in our laboratory to assess various water parameters. This includes specialized tests for marine tanks, as well as unique tests tailored to the Aqua scaping hobby for optimal plant growth. We also provide products to correct water issues and care products for reptiles.
