後頜魚

關於後頜魚

Jawfish are charming saltwater fish that dig burrows in the sand and peek out with just their faces. Learn about their temperament, care difficulty, adult size, lifespan, and feeding needs.

迎接後頜魚前需要了解的7件事

1. 1Needs a sand burrow

   Jawfish dig their own burrows in the substrate and use them as a home base. Provide a deep bed of appropriately sized sand along with sturdy rockwork so the burrow entrance doesn't collapse.

2. 2Shy, skittish nature

   Jawfish are sensitive to sudden movement and noise, darting into their burrows at the first sign of trouble. Avoid startling them near the tank, and they'll gradually grow more comfortable over time.

3. 3Prone to jumping out

   Many jawfish are known jumpers and can leap out of an uncovered tank. A secure lid or cover is essential for keeping them safe.

4. 4Pair with calm tankmates

   Aggressive tankmates can keep jawfish too intimidated to leave their burrows. Choose peaceful, even-tempered fish as companions instead.

5. 5Mainly frozen foods

   Jawfish are typically fed frozen or prepared foods delivered near their burrow entrance. Since they rarely stray far from home, target feeding nearby helps reduce leftover food.

6. 6Some are mouthbrooders

   In certain species, males incubate fertilized eggs in their mouths until they hatch. If you observe this behavior, avoid disturbing the tank and let it proceed undisturbed.

7. 7Lives 3 to 7 years

   Adults stay compact at 5 to 12 cm and typically live 3 to 7 years. Because they're a long-term commitment, consistent water quality and substrate maintenance matter.
