**Wichmann’s Mouth Almighty** (*Glossamia wichmanni*) is a distinctive species of freshwater fish found primarily in northern Australia and Papua New Guinea. Here’s a detailed look at this fascinating species:
1. **Habitat**: Wichmann’s Mouth Almighty inhabits clear, slow-moving freshwater rivers and streams. They are commonly found in areas with abundant vegetation and submerged logs or debris, which provide shelter and hunting grounds.
2. **Appearance**: This species has a robust, somewhat compressed body with a large mouth, characteristic of mouth almighties. Their coloration ranges from silver to pale brown, often with darker spots or streaks that help them blend into their surroundings. This camouflaged appearance is beneficial for both hunting and evading predators.
3. **Size**: Adults typically grow to about 20 centimeters (8 inches) in length, though they can vary slightly depending on environmental conditions and availability of food.
4. **Diet**: Glossamia wichmanni is a carnivore, preying on smaller fish, crustaceans, and various invertebrates. Their large mouths allow them to effectively capture and consume larger prey relative to their size.
5. **Behavior**: One of the most notable behaviors of Glossamia wichmanni is their mouthbrooding. After spawning, the male takes the eggs into his mouth to protect them from predators. He continues to carry the eggs until they hatch, and even for a short period after hatching, providing a safe environment for the young fry until they are ready to fend for themselves.
6. **Reproduction**: During breeding, females lay eggs on a substrate, which are then fertilized by the male. The male immediately takes the fertilized eggs into his mouth for brooding. This parental care significantly increases the survival rate of the offspring.
7. **Aquarium Care**: In captivity, Wichmann’s Mouth Almighty requires a well-planted tank with plenty of hiding spots created by rocks, driftwood, and plants. They thrive in clean, well-oxygenated water with a moderate current. A varied diet of live or frozen foods like brine shrimp, bloodworms, and small fish is essential to keep them healthy.
8. **Conservation Status**: Currently, there are no major conservation concerns for this species. However, as with many freshwater species, they can be affected by habitat destruction, pollution, and changes in water flow. Conservation efforts focus on maintaining clean and stable freshwater ecosystems.
Wichmann’s Mouth Almighty is a unique and interesting species, particularly for aquarium enthusiasts interested in observing their fascinating mouthbrooding behavior and predatory habits.
