The Tyrannochromis macrostoma, also known as the Big Mouth Hap, is a large, powerful predatory cichlid from Lake Malawi, East Africa. The “F1” designation means this fish is first-generation captive-bred from wild-caught parents, offering the closest appearance and behavior to wild specimens. Known for its massive mouth, intense aggression, and bold colors, it’s a centerpiece fish for advanced aquarists with large predator setups.

Is F1 Tyrannochromis macrostoma Right for You?

Q: I just completed my order, what's next?
A: Before shipment, we quarantine all fish for at least 24-48 hours. During this period, we closely monitor the fish to make sure they are healthy. We also do not feed them during this time in order to 'clean out' their digestive system and limit their ability to soil the water. This helps reduce the amount of waste in the bag and will keep the water clean.
