1.A labyrinth fish has the unique ability to breathe oxygen directly from the air and also take in oxygen from its gills. As a result, bettas and other labyrinth fish can survive for short periods of time out of water and if needed, can inhale the air around them (provided they stay moist.)
2.Wild betta fish are a dull greyish-green with short fins; nothing like the spectacularly colored, long-finned beauties of today! Through selective breeding, a wide range of colors and fin types have been developed, including: veil, delta, halfmoon, crowntail, double tail and many more.
