Tank raised Altum angelfish, produced and offered in the USA. The strain originated from the Rio Orinoco and develops a metallic blue forehead. This is a long captive line of several generations developed in Germany, the advantage in this being the fish are exceptionally hardy, can live comfortably at lower temperatures than wild Altums, and reach an astounding size. Reaching maturity in 1 year these fish can grow to 12 inches tall in 2 years and some males eventually attaining 17 inches. A large tank is needed to accommodate their fast growth with height being an important factor. Fish have been well cared for and raised in lots of space to insure proper growth. Fish are adapted to ph 7.2. But, they can adjust to all water conditions.
