Macrostoma Male (IB217SR) – Detailed Product Description

Species Overview

The Macrostoma Male (IB217SR), also known as Betta macrostoma, is a highly prized wild betta originating from Borneo, Indonesia. This “Super Red” locality is valued for its exceptionally vivid red coloration and rare availability in the aquarium trade. Unlike mass-produced ornamental bettas, Macrostoma maintains its natural genetics, body structure, and behaviors, making it a true collector’s species.

It is perfect for hobbyists seeking a striking, rare wild betta for softwater, blackwater, or biotope-inspired aquariums.

🌟Appearance & Coloration

Brilliant deep red to crimson body coloration (“Super Red”)

Subtle iridescent highlights along fins and body under proper lighting

Rounded, wild-type fins

Compact adult size of 4–6 cm

Intensity of red coloration improves in soft, acidic water

The vivid red makes this species a stunning centerpiece in any planted or blackwater aquarium.

🌟Temperament & Behavior

Peaceful in general, but males become territorial during breeding

Paternal mouthbrooder: male carries eggs until fry hatch

Active swimmer, mostly mid-to-lower water levels

Prefers shaded areas, leaf litter, and hiding spots

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 habitats

Dense plants, driftwood, and leaf litter to create natural hiding spots

Secure lid required as bettas are jumpers

🌟Water Conditions

Macrostoma thrives in soft, slightly acidic water:

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) are recommended to maintain stability.

🌟Aquascaping Recommendations

Dark substrate to enhance red coloration

Driftwood, leaf litter, and Indian almond leaves for tannins

Floating plants for shaded areas

Dense planting to reduce stress and encourage natural behavior

A blackwater-style aquascape enhances both color and comfort.

Live or frozen brine shrimp

Daphnia

High-quality micro pellets for bettas

Feed small portions 1–2 times daily. Remove uneaten food promptly to preserve water quality.

Male territoriality increases during breeding
