Choosing the right tank mates for Green Terror Cichlids is not an easy task.
Due to their adult size and voracious appetite, Green terror Cichlids can be difficult to keep in a tank with other species of fish. It’s not all bad, though, there are some good options.
Good tank mates for a Green Terror Cichlid include Jack Dempsey Cichlids, Texas Cichlids, Corydoras, and Oscars. Because they are large and tend to be aggressive, Green Terrors do not make good tank mates with most other common community fish.
One word of warning, if you want to add Cichlids into your tank later, you may have a problem as established Cichlids can attack the newer fish.
So, let’s take a look at 15 potential tank mates for your Green Terror Cichlid.
First, let’s take a look at our first tank mate – Cory Catfish. Cory catfish are one of the best tank mates for Green Terror Cichlids because they are peaceful towards other fish and have no problem living in freshwater conditions.
One advantage of this species of catfish is that they need less room than other larger types. For instance, on average the Cory Catfish grows to a length of about four inches and will do fine in a 10 gallon tank.
Generally, this kind of fish enjoys the company of several other Cory Catfish, so perhaps a few of them should be kept together. They will usually eat at the bottom of the tank and are good cleaners of the tank environment, eating algae as well as many other kinds of food.
This one is often considered as a great choice of Cichlid for beginners because it is easy to care for and fairly tolerant of a wide range of water conditions. Males can grow to 6 inches long and females to about 5 inches in length. They do grow to this size fairly quickly.
One individual fish can live happily in a 30 gallon tank, however if you have a pair, consider putting them in a larger 40-55 gallon tank.
In my experience, this Cichlid tends to avoid conflict as much as possible, which together with its size, makes it a compatible tank mate for the Green Terror Cichlid.
Firemouth Cichlids are mostly peaceful and will not bother other fish as long as they are not overcrowded. Just be aware that even though they are less aggressive than many other Ciclids, they can be territorial. Generally, they can be mixed with most other types of community fish and they should typically get along well with your Green Terror.
The Firemouth Cichlid likes to hide in plants and driftwood.
German Blue Ram
German Blue Ram is a species of freshwater fish which is found in Asia and Africa. It grows to between 2 and 2.5 inches long, so it’s not very large. These fish can live as long as four years, which is rather less than other species of fish you may consider for your tank.
German Blue Rams are mostly peaceful as long as they have the right tank conditions, or are not laying eggs.
They will eat most kinds of aquarium food as well as shrimp and some live foods.
The German Blue Ram fish is very easy to breed and maintain in an aquarium. It’s also an attractive looking, brightly coloured species of fish. Two of these can be placed into a tank of only 20 gallons capacity. So it doesn’t need the kind of space that other fish mentioned here need.
The German Blue Ram likes hiding in caves or under rocks.
The Jack Dempsey fish is a beautiful, colorful freshwater fish that reaches about 4 to 5 inches in length. This is a popular fish for all types of aquariums because it’s good with other peaceful fish and it’s very hardy and easy to care for.
Jack Dempseys will spend the majority of their time at the lower levels of your fish tank. They also need a large tank, at least 55 gallons, but the more the better.
Other fish in the same tank should match the Jack Dempsey’s aggressive nature and should be of a big enough size to hold their own.
This fish eats meat and so small fish, snails and so on are seen as suitable snacks.
Texas Cichlids are omnivores that feed on plants as well as insects, larvae, algae, plankton and fish eggs. The Texas Cichlid is a freshwater fish that is native to the Rio Grande basin. This fish needs a large tank at least 55 Gallons or double that for a pair. The tank conditions are approximately the same as that needed by the Green Terror Cichlid.
They are solitary fish that can be aggressive. They are quite adaptable to differences sources of food and this means they are easy to put into an aquarium which is suitable for other fish, many of them mentioned on this page.
According to former owners, this fish, if fairly large, can just hang out with the Green Terror Cichlid without any problem. However, this is not always guaranteed.
The Chocolate Cichlid is an anglerfish found in freshwater habitats of central Africa. It has a brownish-black color with red or yellow dots on its body. It can grow up to 12 inches long.
The Chocolate Cichlid loves to bury itself under gravel or sand. With time, it can re-arrange these particles to create hiding places for itself.
Generally, though, this fish is quite calm and is suitable as a tank mate for the Green Terror Cichlid.
They are said to be intelligent and have a fun character. This is part of the reason why they are so popular. They are big fish and suited to a larger tank. They also can eat live smaller fish, insects and so on.
Nowhere near as aggressive as other large cichlids, they are big softies with great personality. They are aggressive eaters and will eat anything they can get into their mouth. According to fishkeepingadvice.com, this fish can have aggressive outbursts, but generally this is not common, so they can be good tank mates with suitable other fish such as the Green Terror Cichlid.
Red Spot Severum
The Red Spot Severum is a peaceful fish as long as other fish in the tank are too large to be eaten.
They are commonly found in the Amazon River basin, and they live in schools of up to 100 individuals. The schools of these fishes can be mixed with other species such as Blue Tetras and Rams.
Red Spot Severums can grow up to 10 inches (25 cm) long, with females being smaller than males. These fishes will tolerate most water conditions. They will eat almost anything, although some live food should sometimes be given in addition to standard aquarium food.
Fire Eels mustn’t be handled because they can give out a powerful electric shock!
Fire Eels are carnivores that typically prey on shrimp bait such as small crabs. You need a big tank to keep one, (probably recommended more than 75 gallons). It is nocturnal and tends to like hiding. It shouldn’t bother larger fish, but it will eat smaller fish and can be aggressive. It will probably spend most of its time during the daylight hours buried at the bottom of the tank. It has been known to grow as large as 1m or 3 feet long, so this fish is a challenge!
Make sure also that your aquarium has a deep enough level of sand or material at the bottom.
A group of, say, three to five of these may be ideal as tank mates for the Green Terror Cichlid, in my experience. I also notice that other owners have found this combination to be a happy one (see this post in Reddit).
Clown Loaches are usually found in the wild in Southeast Asia. They have a lifespan of up to 3 years and they can grow up to 5 inches long, sometimes more.
Clown loaches are very colorful fish with a variety of colors including red, blue, orange, purple, yellow, white and black. Clown loaches are bottom dwellers that prefer living at depths of over 10 feet deep with an occasional foray to the surface for air.
Clown loaches live in freshwater and prefer temperatures between 22-26 degrees Celsius.
A small group of these fish would be a good choice to share the tank with a Green Terror Cichlid.
Silver Dollar Fish are native to Florida. They are typically found in ponds, canals, and water with plenty of vegetation.
The Silver Dollar is a peaceful fish that can be kept in an aquarium or pond with other fish. The Silver Dollar prefers water with a pH of 6.5-7.5 and temperatures between 72-81 degrees Fahrenheit (22-27 degrees Celsius).
This fish will occupy the lower levels of any fish tank and is nocturnal in nature.
The birchir is a small predatory catfish that lives in the Amazon River basin.
Birchirs are opportunistic predators and have been known to eat everything from shrimp to tadpoles to insects to other smaller fry. Birchirs can be up to 8 inches (20 cm) long and they live up to 12 years.
Generally, this species of fish will not be aggressive to other large fish and can be kept in a community tank with other fish such as the Green terror Cichlid.
The Yellow Bullhead is a catfish of the order Siluriformes, family Ictaluridae, and genus Ictalurus. Bullheads can be found in rivers, lakes and ponds throughout eastern Canada and the United States.
The Yellow Bullhead is easy to care for and can thrive in a variety of environments. The tank should have a deep area for hiding. This does not mean large rocks or other structures, but rather an area that drops off so that your fish can feel safe when they enter it.
Blood Parrot Cichlid
There may be some adjustment time needed, but after this they should get along fine with your Green Terror Cichlid.
The Blood Parrot has a lifespan of 10-12 years in captivity.
A Blood Parrot will grow to be between six inches and two feet long. They are typically found in densely grown areas with vegetation such as bushes, plants, and rocks which can provide hiding places from predators.
Banded Leporinus are small, colorful fish that use their bright colors to communicate with predators.
They inhabit the shallow waters of the Amazon basin and are endemic to Brazil. The banded Leporin is an omnivore that feeds on plants and algae as well as smaller invertebrates like insects, worms, or snails.
What are the aspects to consider when choosing tank mates for green terror cichlids?
Choosing the right tank mates for green terror cichlids needs careful thought. There are many factors that you need to consider before picking the right tank mates which include:
