About the Firemouth Cichlid
The Firemouth Cichlid (Thorichthys meeki) is a freshwater fish. It comes from Central America, mainly rivers in Mexico and Belize. Its name comes from the bright red color under its jaw. The body is blue-green with some dark stripes. Males are larger and more colorful than females.
Firemouth Cichlids grow to about 6 inches (15 cm) long. They live for 8 to 10 years with good care.
Tank Setup for Firemouth Cichlids
Choosing the right tank is very important for your fish’s health. Here are the key points:
- Tank Size: At least 30 gallons (114 liters) for one Firemouth. Bigger tanks are better if you keep more fish.
- Water Temperature: Keep water between 75°F and 86°F (24°C to 30°C).
- Water pH: The ideal pH is 6.5 to 8.0. Firemouths like slightly acidic to neutral water.
- Water Hardness: Moderate hardness, between 8 and 15 dGH.
- Filtration: Use a good filter to keep water clean. Firemouths produce waste that can harm water quality.
- Substrate: Sand or fine gravel works best. They like to dig in the substrate.
- Decorations: Add rocks, caves, and plants. These give hiding places and help reduce stress.
Important Tank Tips
Firemouths like space to swim. Avoid overcrowding. Change 25% of the water every week. This keeps the tank clean and healthy.

Feeding Your Firemouth Cichlid
Feeding is simple. Firemouth Cichlids eat many kinds of food. Offer a mix of dry, frozen, and live foods for best health.
- Dry Food: Use high-quality cichlid pellets or flakes.
- Frozen Food: Bloodworms, brine shrimp, and daphnia are good choices.
- Live Food: Occasionally feed small live worms or insects to add variety.
- Vegetables: Offer blanched peas, spinach, or zucchini sometimes.
Feed small amounts 2 to 3 times daily. Remove leftover food after 5 minutes. This helps keep water clean.
Firemouth Cichlid Behavior and Temperament
Firemouths are peaceful but can be territorial during breeding. They show bright red color when stressed or defending territory.
They enjoy digging and moving gravel. This is normal behavior. Provide hiding spots to lower stress. Firemouths are best kept in pairs or small groups. Avoid keeping one alone because they like company.
Tank Mates For Firemouth Cichlids
Choose tank mates carefully. Firemouths can be aggressive during breeding. Good companions include:
- Electric Blue Acara
- Severum Cichlids
- Silver Dollars
- Plecos (larger species)
- Colombian and Buenos Aires Tetras
- Giant Danios
Avoid small fish like neon tetras. Firemouths may eat them.
Breeding Firemouth Cichlids
Breeding Firemouths is possible in home aquariums. They form strong pairs and protect their eggs well.
To breed Firemouths:
- Have a mature pair (at least 6 months old).
- Keep water temperature around 80°F (27°C).
- Provide flat rocks or broad leaves for egg laying.

The female lays eggs on a flat surface. Both parents guard the eggs. Fry hatch in about 3 to 5 days. Parents protect fry for several weeks.
