For more than 20 years now, we have been conducting expeditions almost every year and have been able to gather valuable knowledge about the waters from which our ornamental fish come. On our expeditions we have carried out numerous tests to gain a more precise understanding of the conditions under which our aquarium fish live in the wild. In this post we have summarised all our measured water values. From one of our first expeditions to Sri Lanka and the Maldives in 2004 to the Japan Expedition in 2019.
