Macrostoma Male (IB111) – Detailed Product Description
Species Overview

The Macrostoma Male (IB111) (Betta macrostoma) is one of the most prestigious and sought-after wild betta species in the aquarium hobby. Native to the blackwater streams of Borneo, this species is treasured by collectors for its rarity, natural elegance, and fascinating breeding behavior.
Unlike ornamental domestic bettas, Macrostoma retains its authentic wild form, refined structure, and calm yet confident temperament. IB111 represents a specific collection line, maintaining pure genetics and traceability—ideal for serious breeders and enthusiasts.

🌟Appearance & Natural Coloration
Deep earthy red to reddish-brown body tones
Subtle darker banding along the body
Streamlined wild-type fin structure
Elegant rounded caudal fin
Adult size: approximately 4–6 cm
Under soft, tannin-rich lighting, the natural red hues intensify beautifully, especially in blackwater setups.

🌟Temperament & Behavior
Generally peaceful and calm
Males may display territorial behavior during breeding
Active mid- to lower-level swimmer
Prefers shaded, structured environments
Exhibits fascinating paternal mouthbrooding behavior
This species thrives in quiet tanks with minimal disturbance and stable water parameters.

🌟Tank Requirements
Minimum tank size: 20–30 liters (5–8 gallons) for a single male
Gentle sponge filtration recommended
Very low water flow
Secure lid required (excellent jumper)
Dim lighting preferred
Add driftwood, botanicals, and leaf litter to recreate natural habitat conditions.

🌟Water Conditions (Very Important for Macrostoma)
Temperature: 24–28°C (75–82°F)
pH: 4.5–6.5 (slightly acidic ideal)
Hardness: Very soft to soft
Ammonia/Nitrite: 0 ppm
Nitrate: Below 20 ppm
Stable soft, acidic water is key to maintaining health and coloration. Regular small water changes (10–20% weekly) are recommended.

🌟Aquascaping Recommendations
Blackwater-style setup preferred
Indian almond leaves or natural botanicals
Driftwood with tannins
Floating plants to diffuse light
Dark substrate to enhance color
Creating a biotope-style tank significantly reduces stress and enhances natural behavior.

🌟Feeding Habit & Diet
Macrostoma Male is strictly carnivorous and prefers:
Live brine shrimp
Daphnia
Mosquito larvae
Frozen bloodworms (occasionally)
High-quality carnivore micro pellets
Feed small portions once or twice daily. Remove uneaten food promptly to protect water quality.

🌟Tank Mates & Compatibility
Best kept in species-only aquarium
Can coexist with very peaceful softwater fish in larger planted setups
Avoid aggressive or fast-swimming species
Avoid fin nippers
This species is best appreciated in a calm, dedicated environment.

🌟Breeding Information
Paternal mouthbrooder
Male incubates eggs in mouth for approximately 10–14 days
Soft, acidic water encourages successful breeding
Fry require live micro foods in early stages
Breeding Macrostoma is rewarding but recommended for experienced aquarists.

🌟Care Level
Intermediate to advanced
Sensitive to water hardness and parameter fluctuations
Requires stable, mature aquarium
Not recommended for beginners without softwater experience

🌟Why Choose Macrostoma Male (IB111)?
This is not just a fish—it’s a collector’s species. Macrostoma Male (IB111) offers authentic wild genetics, rare availability, and fascinating mouthbrooding behavior. With proper softwater care and a blackwater-inspired setup, it becomes a true centerpiece for serious aquarists.
