Peacock Eel Tank Mates – What You Need to Know
Getting tank mates for your peacock eel is easy when you know exactly what your peacock eel needs to be happy. Youโll also need to understand what types of fish to stay away from, and why! In the interest of keeping you informed, weโve detailed all of the factors you should be aware of when looking for the best peacock eel tank mates.
Temperament
Temperament of a fish, or an eel, refers to what kind of attitude the animal has toward the other creatures and elements it is surrounded by. A peacock eel, for example, is very peaceful, not acting in aggression toward other creatures of a similar size.
What this means is that youโll need a fish with similar peaceful personalities as a tank mate, otherwise you could have a bullied eel in your tank!
Size
Size is another important factor to consider. If your peacock eel is much bigger than its tank mates, even with its peaceful nature, you could find it hunting smaller animals. On the flip side, if your peacock eel is much smaller than the big tank mates youโve picked out, youโll find it running for its life more often than not!
To be safe, get fish that are between 2 and 12 inches, with 5 to 6 inches being the sweet spot when it comes to tank mates for a peacock eel.
Competition
Competition mainly refers to feeding time in your aquarium. A peacock eel generally eat during the evening or night time, and they love crustaceans, worms, and of course, insect larvae, which can all be either live or frozen.
The danger comes when the tank is full of fish who eat the same sorts of food at the same time, and might be faster or more aggressive than the peacock eel and steal its food. To avoid this outcome, tank mates should not eat at the same time, in the same zone of the tank, or the same exact favorite foods as the peacock eel.
Parameters ; Tank Setup
Finally, it is important to take note of the parameters and tank setup of a peacock eel. You will want tank mates that live in similar conditions. A peacock eel enjoys a tank size of 40 gallons, if not more. This space should be filled with driftwood and other places for the eel to hide in and out of.
The temperatures are important, too. Peacock eels survive in a temperature that is between 73 and 79 degrees Fahrenheit. Fish that are meant to be tank mates with the peacock eel must be able to comfortably and healthily live in the same temperature!

- Adult Size: 6 inches
- Compatible With: Peacock Eel
- Care Level: Medium Difficulty
- Origin: Guyana and Brazil
Silver Dollars are certainly a unique contrast, visually, to your longer and more dappled peacock eel. Silver Dollars are medium-sized fish with plain but shiny silver bodies. Their snub faces will give your tank a pleasing variety next to the long peacock eel.
One of the greatest things about silver dollar fish is that they are suitable to live in a community tank and their peaceful nature matches up perfectly with peacock eels.
Pros of keeping with Peacock Eel:
- No infighting
- No competition for food
Cons of keeping with Peacock Eel :
- None!
2. Hatchetfish
- Scientific Name: Gasteropelecidae
- Adult Size: 2 inches
- Compatible With: Peacock Eel
- Care Level: Medium Difficulty
- Origin: Brazil, Peu, Bolivia, and Columbia
Because the Hatchetfish dwells mainly in the top of the tank and does not worry about bothering other fish, its temperament already makes for a great match for your peaceful peacock eel. However, hatchetfish have more to offer as tank mates.
Visually, they are already pretty striking. Shaped like the blade of a hatchet and coming in a variety of colors from speckled reddish brown to a silvery blue, these fish will make great accompaniments to your peacock eel!
Pros of keeping with Peacock Eel:
- No infighting
Cons of keeping with Peacock Eel :
- May compete for insect larvae food
3.ย Blood Parrot Cichlids
- Scientific Name: Amphilophus citrinellus x Vieja synspilum
- Adult Size: 8 inches
- Compatible With: Peacock Eel
- Care Level: Easy
- Origin: Man-Made
Blood parrot cichlids make great tank mates for Peacock eels as long as they are given plenty of places to hide and room to swim. Their temperament is usually semi-aggressive, but only with other fish that are territorial. Therefore, with a peaceable peacock eel, this cichlid will have a calm life!
It is also worth noting that blood parrot cichlids will not eat the same foods as a peacock eel and so pose no threat. They are also beautiful, bred for their fiery color and beak-shaped head, as well as a small mouth.
Pros of keeping with Peacock Eel:
- No food competition
Cons of keeping with Peacock Eel :
- Normally peaceful, but may become aggressive without enough room.
4. Lemonpeel Angelfish
- Scientific Name: Pomacanthidae
- Adult Size: 5 inches
- Compatible With: Peacock Eel
- Care Level: Medium Difficulty
- Origin: Indo Pacific Ocean
Also known as the lemon peel angel and dwarf angelfish, this is one of the prettiest types of angelfish you can find in aquarium communities. They are particularly beloved for their bright yellow color set off with electric blue and white accents, like the rings around their yellow eyes.
These angelfish are semi-aggressive, but only if they are not givven enough room in their zones on the bottom and middle of the tank, and only if they are threatened by nosy or aggressive tank mates. Since the peacock eel does not fit those descriptions, you should be good to go with the lemonpeel angelfish!
Pros of keeping with Peacock Eel:
- No food competition
Cons of keeping with Peacock Eel :
- Can become aggressive without enough room.
5. Kissing Gourami
- Scientific Name: Helostoma Temminkii
- Adult Size: 12 inches

- Origin: Thailand, Sumatra, Vietnam, Borneo, Cambodia, Java, Malay, Myanmar
A kissing gourami is named for its long, puckered lips and behavior of kissing one another between males! They are generally a pale rosy color, with a simple but pleasing classic shape and short fins.
Kissing gouramis make great tank mates with peacock eels because, though they can be aggressive with fish that are much smaller, they do not get much larger than peacock eels themselves. They simply need enough room and obstacles in the tank to feel comfortable and avoid violence!
Pros of keeping with Peacock Eel:
- No food competition
Cons of keeping with Peacock Eel :
- Can become aggressive without enough room.
6. Forktailed Rainbowfish
- Scientific Name: Psuedomugil furcatus
- Adult Size: 2 inches

The forktailed rainbowfish adds not only bright cheery color to a tank, but a peaceful nature that will combine nicely with a peacock eel. They are blue-eyed, silver in color, accented with yellow striping and matching yellow fins.
These fish are great community tank members, but only if they have enough of their own kind to mingle with. This helps the fish to feel safe rather than stressed. Keep 6 rainbowfish together.
Pros of keeping with Peacock Eel:
- No food competition.
- Peaceful.
Cons of keeping with Peacock Eel :
- None!
7. Swordtails
- Scientific Name: Xiphophorus helleri
- Adult Size: 3 to 4 inches

Swordtails are a no-brainer if you are looking for a great fish to keep with peacock eels. They are naturally green in the wild, but in captivity they come in more variety, such as neon, painted, and red and yellow. All variants have long fins and bar-like stripes.
They should be kept in groups of at least four for their own comfort, but they will breed quickly if kept with the opposite sex! However, their peaceful natures mean they will cause no trouble for your peacock eel.
Pros of keeping with Peacock Eel:
- No food competition
- Non-aggressive.
Cons of keeping with Peacock Eel :
- None!
8. Rainbow Kribensis
- Scientific Name: Pelvicachromis pulcher
- Adult Size: 4 inches
- Compatible With: Peacock Eel
- Care Level: Easy
- Origin: Africa
The rainbow kribensis has gone by many names, including purple cichlid, king cichlid thanks to its royal coloration, and the shorter โrainbow krib.โ The rainbow krib earns all of its titles from its beautiful color. It can be purchased in just about every color on the spectrum, with sporty sharp fins and a longitudinal stripe spanning the body.
The rainbow kribensis is great as a tank mate thanks to omnivorous diets that will keep it from eating all of the reacock eelโs food, and the peaceful nature they generally have. They are, however, territorial, and though they canโt really harm an eel, they may nip other cichlidโs fins if not provided with their own space.
Pros of keeping with Peacock Eel:
- No food competition
- Generally peaceful
Cons of keeping with Peacock Eel :
- Can become territorial with other fish if kept in too small a space
9. Reticulated Hillstream Loach
- Scientific Name: Sewellia lineolata
- Adult Size: 3 inches
- Compatible With: Peacock Eel
- Care Level: Easy
- Origin: Asia
This is a smaller breed of fish, but you will find that itโs beautiful yellow-to-tan coloration and spotted pattern matches well, visually, with your peacock eel! Not only that, this species generally occupies the bottom of the tank and is peaceful in nature.
Finally, one of the greatest perks of this species is that it will eat algae in the tank! Though it likes frozen and live foods, too, it is unlikely to compete for food with the peacock eel.
Pros of keeping with Peacock Eel:
- No food competition
- Cleans algae
- No aggression
Cons of keeping with Peacock Eel :
- None!
10. Bristlenose Pleco
- Scientific Name: Ancistrus cirrhosus

- No food competition
- No aggression
- Cleans Tank Floor
Cons of keeping with Peacock Eel :
- None
11. Yoyo Loach

- Care Level: Medium Difficulty
- Origin: India
A silvery loach with the letters O and Y in the pattern of dark markings on its back, giving it its name. This fish thrives in a community of three or more of its own kind, as it is very social.
That being said, the yoyo loach will make an excellent companion for a peacock eel thanks to its love for peaceful neighbors and lack of interest in anything but the peacock eelโs leftovers after feeding time!
Pros of keeping with Peacock Eel:
- Not aggressive
- No food competition
Cons of keeping with Peacock Eel :
- None!
12. Zebra Loach
- Scientific Name: Botia striata
- Adult Size: 4 inches
- Compatible With: Peacock Eel
- Care Level: Easy
- Origin: Southern India
Named for its stripes, this fish is a stylish visual component to any tank. Add that to a peaceful nature, and youโve got a great community fish.
The emphasis is on community, however; while your zebra loach wonโt bother your peacock eel, it will really be happiest in a group of five or more of its own kind.
Pros of keeping with Peacock Eel:
- No aggression
- No food competition
Cons of keeping with Peacock Eel :
- None
13. Pearl Gourami
- Scientific Name: Trichopodus Leerii

The pearl gourami is long and thin, much like itโs fins. It has a type of โmother of pearlโ look to it, and is always marked by a long black line ending in a characteristic spot!
This small fish makes for a great tank mate for a peacock eel because it is devoted to peace, and doesnโt do well with aggressive fish. It loves to be kept with fish near the same size and temper.
Pros of keeping with Peacock Eel:
- No food competition
- No aggression
Cons of keeping with Peacock Eel :
- None
14. Paradise Fish
- Scientific Name: Macropodus opercularis
- Adult Size: 4 inches
- Compatible With: Peacock Eel
- Care Level: Easy
- Origin: Asia
This fish does have a few semi-aggressive tendencies, but like others on this list, this is mainly due to poor amounts of room. The paradise fish tends to fight with any species that is larger and aggressive; it always wants to be king of the tank! However, peacock eels are not aggressive, so they should get along well together.
A paradise fish is striped in several beautiful, iridescent colors, sometimes red, green, orange, and blue. These are speckled, as well, making a pleasing change of scenery in your tank.
Pros of keeping with Peacock Eel:
- No food competition
- No aggression as long as it is dominant.
Cons of keeping with Peacock Eel :
- None!
15. Chocolate Gourami
- Scientific Name: Sphaerichthys osphromenoides

- Care Level: Difficult
- Origin: Malacca, Sumatra, Borneo
This fish is well known and liked for itโs oval body and dark color, much like chocolate! This brownish hue is interspersed by around five stripes colored yellow or white, with a forked tail.
These fish are slow and shy. They do not do well in any environment where they have to compete with more boisterous fish for food. Luckily, this makes them a great pairing with peacock eels!
Pros of keeping with Peacock Eel:
- No food competition
- Peaceful
Cons of keeping with Peacock Eel :
- None!
In Conclusion
To sum everything weโve learned up, the 15 best Peacock Eel Tank Mates include larger and more peaceful fish such as the paradise fish, several gouramis, and even loaches. As long as the fish are able to live in temperatures and conditions that coincide with the preferences of a healthy peacock eel, and are large enough to avoid being hunted, youโll have no trouble!
However, if the fish are not peaceful and are both larger than the peacock eel and aggressive, you may find yourself with problems. Look for fish that will not compete for the same nocturnal food choices as your eel, and will mind their own business peacefully. Youโll enjoy a vibrant and diverse tank in no time!
