Once more we were able to import a real jewel among the tetras for the first time ever: Tucanoichthys tucano. This tiny little species attains a maximum length of around 2 cm and is thatfore an ideal fish for nano aquaria. Tucanoichthys lives endemic in the upper Rio Negro basin, to be more precise in the Rio Uaupes. Fishes from that region should be kept in very soft, strongly acidic water (pH 5). The water should be coloured brownish with humidic acids. Males have red in the caudal and anal fin, which is missing in females.
In dark aquaria the pastel, but shining colours of the fish are presented best.
