F1 Altum Angelfish

F1 Altum Angelfish (Pterophyllum altum)

First-generation captive-bred from wild Altum parents, F1 Altums offer the majestic size and presence of wild fish with the added hardiness of being tank-raised. Taller and deeper-bodied than common angelfish, they're a rewarding showpiece for experienced keepers with large, well-maintained tanks.
