Temperature

22〜28℃

Diet

Frozen and live foods (Daphnia, Artemia, bloodworm), dried foods

Tank

From a 45 x 30cm tank (about 41 litres) for a pair. Provide floating plants and wood for cover near the surface, and fit a tight lid.

Water Temperature & Quality

22-28C, pH 5.5-7.5, 1-10 dGH. It comes from still and slow water, so avoid strong flow.

Tank Mates

Not recommended for a standard community tank. Keep alone, or with very peaceful species such as small cyprinids and loaches from similar habitats.

Diet & Feeding

It eats small aquatic invertebrates in the wild. In captivity offer Daphnia, Artemia or bloodworm regularly alongside dried foods.

Breeding & Spawning

A bubble-nester. The male builds the nest and guards eggs and fry alone; eggs hatch in 24-48 hours and fry swim free 3-4 days later, starting on infusoria.

Health & Notes

Keep surface access clear for air breathing and do not let the air above the water get cold. Males fight, so do not house them together outside breeding.

About Emerald Betta

A wild betta species from Thailand and Laos, known for its greenish metallic sheen. Grows to about 6-7cm and suits solitary keeping at an intermediate difficulty level.

7 things to know before welcoming a Emerald Betta

1. 1Best Kept Alone

   Emerald Bettas are strongly territorial and generally don't do well in typical community tanks. Two males housed together can fight fiercely, and pairing them with other species also requires careful consideration. Solitary keeping is the recommended approach for enjoying this fish at its best.

2. 2An Intermediate-Level Fish

   This species is generally considered suited to intermediate-level keepers. It can respond differently to water quality and environmental changes compared to common commercially bred betta varieties, so it's worth researching care requirements before bringing one home.

3. 3Grows to About 6-7cm

   Adults reach approximately 6 to 7cm in length, a fairly typical size for a betta. Since it's usually kept alone, this size is manageable within a reasonably modest setup. When preparing the tank, picture the fish's full-grown size, not just how it looks when first brought home.

4. 4Delicate, Shimmering Fins

   The greenish metallic sheen that gives this species its name extends into the fins, making them a real visual highlight. That said, betta fins are thin and delicate, so it's best to avoid sharp-edged decorations or rough substrate that could damage them.

5. 5Breeds by Building Bubble Nests

   Males build bubble nests at the water's surface and guard the eggs and fry within them, a classic betta breeding behavior. Even if you're not planning to breed, watching this behavior unfold is one of the species' quiet pleasures. If you spot a bubble nest, avoid strong water flow that could disturb it.

6. 6Set Up the Tank Before Arrival

   Prepare a tank suited to solitary keeping along with a lid, since bettas can jump. They also surface periodically to gulp air, so it's important to leave enough open space near the water's surface.

7. 7Watch for Signs of Good Health

   Keeping an eye on appetite, coloration, fin condition, and swimming behavior is the basis of everyday health monitoring. If something seems off for more than a short while, it's a good idea to consult someone knowledgeable or a veterinarian promptly.
