Cardinal tetra habitat in the lower rio negro, Brazil. This blackwater stream had a low ph of 4.2 and was extremely soft with a undetectable kh and gh level and a tds of 4! Air temperature was 30c and water temp around 27c You could mimic this habitat with RO water and an inert sand substrate, added wood and leaves will produce mild tannic acids and drive down your pH. Giving you the perfect cardinal tetra biotope tank!; #cardinal #tetra #cardinaltetra #fish #blackwater #biotope #aquascaping #ha
