# Half Black Veil Angelfish The Half Black Veil Angelfish carries its distinctive coloration like a natural tuxedo?solid black extending across the rear half of its body while the front gleams in silvery white. Native to South American river systems, particularly slow-moving tributaries of the Amazon, this fish developed its compressed, disc-shaped body to navigate dense vegetation and narrow spaces between submerged branches. That elegant veil-like extension of the dorsal and anal fins isn't just decorative; it's how the fish communicates its mood and intent to others in the tank, flaring noticeably when establishing territory or responding to rivals. Don't mistake the moderate care requirement for simplicity. This fish thrives when given the right rhythm: stable temperatures between 74-82øF, slightly acidic water, and gentle filtration that won't create strong currents (they naturally prefer calm environments). A 20-gallon tank serves as the minimum, but these fish benefit from vertical space rather than sprawling footprints?they'll spend considerable time cruising mid-water column rather than exploring the substrate. Live or artificial plants serve dual purposes: they provide security and shade, which this fish actively seeks, while also giving it something to weave through during its daily patrols. The semi-aggressive tendency reveals itself during breeding season or when multiple males share tight quarters, but in appropriately sized tanks with adequate sightlines and retreat spots, they coexist reasonably well with similarly-sized peaceful community fish. They're curious about their surroundings and will investigate changes to d‚cor or new tank mates with deliberate interest. With proper care, these fish readily reach 6 inches and can remain active members of an aquarium for a full decade, developing distinct personalities and recognition of their keepers over time.
