Gold Tetra (Hemigrammus rodwayi)

The Gold Tetra is one of the cutest characins. It has a golden hue on its silver-based skin, small in diameter, but moves usually in groups of 5 or more, which is a sight to see in any aquarium or natural habitat. It gets the golden hue from ‘guanin’, a natural process of secretion in its skin to protect itself from some parasites, because the gold tetra has natural predisposition to contract the trematode parasite.
