Additional Information
From the beginning it was a small dream of a shoal of cardinaltetras in a 100 liters. Then I was curius from where they came and what conditions they preferred. The result is a paradoxal combination between design, biotopeambition and materials available. The aim was a blackwater stream, but in time I'll get there.
