Mouth Almighty

A broad-mouthed freshwater predator associated with the Australian and New Guinean fish Glossamia aprion. Its understated coloration and ambush-feeding behavior make it a specialist display fish.

Aquarium and care

Plan for an adult around 18–20 cm and a spacious mature aquarium with cover, open areas, and strong filtration. Maintain stable warm freshwater and secure the lid. Its mouth size and feeding behavior matter as much as its body length when choosing housing.

Feeding

Offer appropriately sized aquatic-based frozen foods and suitable carnivore foods. Some individuals need patience to accept prepared foods; do not rely on routine live feeder fish.

Temperament and tank mates

Small fish and shrimp are prey. Keep only carefully selected companions too large to swallow, and monitor interactions closely.
