Species Overview

The Macrostoma Male (IB118) (Betta macrostoma) is a highly sought-after wild betta from Borneo, Indonesia. Known as the “Super Banding” strain, this fish is prized for its striking banded body pattern, vivid coloration, and preservation of authentic wild genetics. Unlike ornamental bettas, Macrostoma maintains its natural behavior and streamlined body shape, making it a true collector’s fish.

Perfect for blackwater or softwater aquariums with biotope-style aquascaping, this species is a showpiece for hobbyists seeking rare wild bettas.

🌟Appearance & Coloration

Distinct bold banded pattern along the body (“Super Banding”)

Deep red to reddish-brown base coloration

Subtle iridescent highlights on fins under proper lighting

Rounded, wild-type fins

Adult size: 4–6 cm

Pattern and coloration are enhanced in soft, acidic blackwater

The combination of vivid bands and natural color makes it a striking centerpiece for planted or blackwater aquariums.

🌟Temperament & Behavior

Generally peaceful, though males are territorial during breeding

Male is a paternal mouthbrooder, carrying eggs until fry hatch

Active mid- to lower-water swimmer

Prefers shaded areas, leaf litter, and dense plants

Best kept in species-only tanks or with carefully selected peaceful tank mates

🌟Tank Requirements

Minimum tank size: 20–30 liters (5–8 gallons) for a single fish

Gentle filtration recommended (sponge filter preferred)

Low water flow to mimic slow-moving blackwater streams

Include driftwood, leaf litter, and dense plants for hiding spots

Secure lid required, as bettas are jumpers

🌟Water Conditions

Temperature: 24–28°C (75–82°F)

pH: 4.5–6.5

Hardness: Very soft to soft

Ammonia/Nitrite: 0 ppm

Nitrate: <20 ppm

Regular partial water changes (10–20% weekly) help maintain water quality and pattern intensity.

🌟Aquascaping Recommendations

Dark substrate enhances band visibility and coloration

Driftwood, leaf litter, and Indian almond leaves create tannin-rich blackwater

Floating plants provide shade and stress reduction

Dense planting encourages natural behavior and territorial boundaries

🌟Feeding Habit & Diet

Macrostoma Male is carnivorous:

Live or frozen brine shrimp

Daphnia

Bloodworms (in moderation)

High-quality micro pellets for bettas

Feed small portions 1–2 times daily and remove uneaten food to preserve water quality.

🌟Tank Mates & Compatibility

Best kept in species-only tanks

Can coexist with small, peaceful softwater fish in heavily planted tanks

Avoid aggressive, large, or fin-nipping species

Male territoriality increases during breeding

🌟Breeding Information

Male is a paternal mouthbrooder

Eggs incubate in male’s mouth for 10–14 days

Soft, acidic water improves breeding success

Fry require infusoria or microworms in early stages

Breeding preserves wild genetics and is rewarding for experienced aquarists.

🌟Care & Maintenance

Intermediate care level

Maintain stable water and soft, slightly acidic conditions

Monitor water quality regularly

Provide shaded hiding areas to reduce stress

🌟Ideal For

Wild betta collectors

Blackwater aquarium enthusiasts
