Cardinal Tetra

Cardinal Tetra

Fire red and reflective blue stripes along the length of this fish helped make the cardinal tetra the most popular aquarium fish in Europe. An entire industry in Brazil is involved in catching and sustaining this species, employing thousands that would otherwise work in deforestation industries. Therefore cardinal tetras are one of the many tropical fish that save the rainforest. So, keeping aquariums prevent global warming.

Cardinals are the most popular fish in the aquarium trade in Europe, second to Glo Fish in the USA. These fish will not tolerate Ph over 7.4, and need good clean water, just like the Amazon.
