Professional products for fish keepers.

Colombo has over 30 years of experience developing water treatments and fish medications for aquariums and pond. Colombo was founded by veterinarian Mario Blom and started with a range of medicines for tropical fish.

Research and development

Our dedicated research and development team is constantly conducting tests to either develop new products or to improve the existing products. It is our goal and mission to provide the best possible products to achieve great results for every fish keeper.

In anything we do we centralise the consumer, we ensure products complete each other and together with leaflets and point of sale material we provide guidance to achieve the best possible results for the end user.


Colombo works on sustainability, packaging, production methods and the products itself are developed and produced with sustainability in mind.
