Aquaheavens Black Copper Halfmoon Male Betta - Live Fish for Aquarium Exotic Freshwater Live Fish
- RARE DARK LUXURY LIVE BETTA FISH — ARMORED IN BLACK & COPPER — The Black Copper Halfmoon Male Betta is one of the most exclusive and visually commanding live betta fish available today. His thick body is cloaked in a rich metallic gray-copper sheen that glows like polished steel under light, while deep black undertones and darkened fin edges create a bold, mysterious contrast — a dark luxury live fish that commands attention in any aquarium without demanding it.
- 🌙 PERFECT 180° HALFMOON TAIL — FULL FAN FLARE — Named for its spectacular tail span, the Halfmoon Betta opens its caudal fin to a full 180 degrees — a perfect semicircle of flowing, dramatic finnage. In the Black Copper variety, this fan tail reveals stunning gradients of dark copper, black, and silvery-gray depending on the light — making every flare and display a breathtaking, ever-changing visual experience that no photograph can fully capture.
- 💪 BOLD PERSONALITY — INTELLIGENT & INTERACTIVE LIVE FISH — This live betta fish is far more than a decorative specimen. He recognizes his owner, responds to movement at the glass, patrols his territory with confidence, and builds elaborate bubble nests when content and healthy. A well-kept Black Copper Halfmoon Betta is one of the most interactive and personable live aquarium fish a hobbyist can own — full of character, attitude, and elegance.
- 🏠 IDEAL SETUP — 5-GALLON MINIMUM, HEATED & FILTERED — For a thriving Black Copper Halfmoon Betta, a minimum 5-gallon heated and filtered aquarium is strongly recommended. Maintain water at 75–82°F with a pH of 6.5–7.5 and near-zero ammonia and nitrite levels. Use a gentle, low-flow filter to protect his flowing fins, add live or silk plants for hiding spots, and keep a secure lid — this live betta fish can jump.
- 🫧 LABYRINTH BREATHER — BREATHES ATMOSPHERIC AIR — Like all betta fish, the Black Copper Halfmoon possesses a specialized labyrinth organ that allows him to breathe air directly from the water surface — a remarkable evolutionary adaptation that makes him more resilient than most live aquarium fish. You will regularly see him rise gracefully to the surface for air, and a healthy male will build floating bubble nests as a natural sign of contentment.
