Top 8 Of The Best Firemouth Cichlid Tank Mates

What could be the best Firemouth Cichlid tank mates when the species is known to be beautiful but semi-aggressive? The species is popular with aquarium hobbyists despite its feisty personality.

They are vibrant freshwater fish that adds color to your tank; you will enjoy seeing them swim and move the colors around. While they require some special treatment, this fish is not high-maintenance.

However, since they are somehow aggressive, you cannot add other fish of similar nature. Take note the Firemouths won’t start trouble unless provoked. So their best tank mates are fish similar in size and aren’t aggressive.

The Best Firemouth Cichlid Tank Mates

You have plenty of options for the other fish you can add as tank mates for your Firemouths for as long as you have a large enough tank.

You only have to make sure that the fish you will add are not aggressive and are similar in size to the Firemouth. The bigger ones might stress them out, and tank mates that are too small might get bullied.

Here are the recommended tank mates for your Firemouth Cichlid:

1. Rummy Nose Tetra

Size: 5 inches

Minimum Tank Size: 20 to 30 gallons

Water Temperature Range: 73°F to 80°F

Diet: Herbivore

Care Requirements: Easy

Temperament: Peaceful

Rummy Nose Tetra

The Rummy Nose Tetra is one of the most popular tetras in the hobby community. It’s hard to find a breeder or store that doesn’t have at least one of these fish on hand.

This little creature is easy to care for, and it’s gratifying to see them grow into a full-grown adult. It is a moderate-sized fish that can grow up to two inches in length.

The fish has a body shape that looks like it has a rumpled nose. It has three stripes running down its body, with one line extending from the head to the base of its tail fin.

The coloration is silver with black spots on top of its body and faint yellow lines running along each side of its body. The fins are also colored this way, with a green and black band running across the back fin, and the other two fins are also colored in a similar fashion.

Rummy Nose Tetras are very social fish, so it’s recommended that you keep at least two in your tank at all times.

They’re active swimmers that enjoy swimming around the bottom of your tank with other Firemouth Cichlid tank mates. This makes them great for keeping with other similar fish.

The Clown Pleco is a slow-moving fish that can grow up to three inches long. It has black and orange spots on its body though there can be variations depending on where it is kept.

It also has two barbels or whiskers hanging from its mouth that it uses for feeding and cleaning itself.

Good water quality, including pH and hardness, is vital because Clown Pleco does not tolerate poor water conditions well. They also need good nutrition for optimal growth, which can be supplemented with protein-rich foods such as bloodworms and Mysis shrimp.

The Clown Pleco is peaceful and can be kept with other fish varieties if compatible. They will become aggressive when two males live together, but once they settle into your tank and get used to each other’s presence, there shouldn’t be any problems.

It also has a large mouth that can hold large amounts of food at a time. It is characterized by its long flowing fins used for swimming or jumping out of the water into air bubbles.

The Rainbow fish is a hardy fish that does not require a lot of space. It is relatively easy to care for and can be housed in most tanks, but they need special attention because they are prone to illness or disease.

It has a peaceful disposition, making it an ideal pet for beginners. The fish prefers to be kept in groups of three or more, but if you don’t have the room, then it’s okay to keep them separately.

Minimum Tank Size: 30 gallons

Temperament: Semi-aggressive

Diet: Omnivorous

Care Level: Easy

The Firemouth Cichlid is a freshwater fish bred in captivity for many years. It is very popular among aquarium enthusiasts because it is easy to care for and has a bright red coloration.

The Firemouth Cichlid is commonly found in the waters of Central America and South America, but it can also be found in many parts of Asia. This freshwater fish can grow up to two inches long and have been known to live up to five years in captivity.


The Firemouth Cichlid is a fish that is native to South America. This fish has two distinct colors, with some being red and others being orange.

The color of this fish varies depending on where it is found. For example, the Firemouth Cichlid found in the Amazon River has a bright red body.

This fish has a long body shaped like a torpedo and a large mouth that opens widely. It can grow up to five to six inches in length.

They have large, reflective eyes, which helps them see at night or in dark waters with little light. The Firemouth Cichlid also has scales on its bodies, although these scales aren’t very big or noticeable.

The scales of this fish species are small and smooth, so they don’t cause any problems for humans when interacting with or touching it during breeding time.

Care Guidelines

The tank size for Firemouth Cichlids should be at least 55 gallons, with a minimum of 30 gallons being the best. The larger the tank, the better for these fish.

They are territorial and need room to swim around without bumping into other cichlids or being stunted by their own bodies.

Firemouth Cichlids need soft, acidic water with a pH of six to seven and a temperature of 75 to 82 degrees Fahrenheit (24-28°C). If you have hard water, you will need to work to keep it as soft as possible by adding salt mix or liquid chlorine to the water regularly (once every two weeks).

You can also add an air stone to help increase oxygenation in your tank by aerating the water. As far as what type of substrate goes in the tank with these cichlids, you can use anything from sand and gravel to plastic plants.

Firemouth Cichlids are susceptible to many diseases, including fin rot and ich. These diseases can be transmitted through water changes and should be avoided at all costs.

The best way to prevent these diseases is by using high-quality, filtered, or bottled water when maintaining your tank. Firemouths will eat almost any food offered to them.

They do not require much variety in their diets as long as there is a high proportion of meaty foods. Most fish stores carry frozen blood worms, brine shrimp, and other quality sources of protein that can be used to supplement an overall healthy diet.

They are peaceful when kept in groups. They are also playful, so you should expect them to spend most of their time swimming around your tank or the tank’s surface.

They will also constantly search for food, so if you don’t feed them often enough, they may become aggressive towards other fish in the tank.
