A small Peacock eel needs to be housed in an aquarium that is at least 61 centimeters long (24 inches) and has a volume of 75 liters (20 gallons). If your Peacock eel grows larger, you must move it to a bigger aquarium. The water conditions in the aquarium should resemble those found in slow flowing Southeast Asian rivers. You can add some salt to the water. The ideal pH is 7.0 and the ideal dH is 10, but the Peacock eel will tolerate a pH between 6 and 8 and a dH in the 6 to 25 range. This fish like warm waters so make sure that the temperature stays between 23 and 28° C (73 and 82° F).
The Peacock eel is commonly kept in community aquariums since it is a quite peaceful fish. Avoid keeping it with small fishes, since they will be considered food. Similarly sized and peaceful fish that appreciates the same water conditions as the Peacock eel are much better companions. When the Peacock eel has been introduced to a new home, it is usually very shy and prefers to stay hidden most of the time. If you provide it with an aquarium environment that makes it feel safe, it can become very friendly over time. As mentioned above, the Peacock eel inhabits densely grown waters, and keeping this fish in an aquarium with plenty of plants is therefore recommended. Your Peacock eel will also appreciate PVC pipes that it can hide inside, and sheltered spots created by rocks, roots and wood.
