The Peacock EelÃÂÃÂÃÂÃÂ Macrognathus siamensisÃÂÃÂ is a very handsome spiny eel. There can be some variation in its color and patterning, depending on where it originates from. But basically they are light brown in color with a thin pale yellow stripe running from the eye to the base of the tail.
You can readily see where the name Peacock Eel comes from. They will generally have between three to six decorative eye spots adorning the upper rear portion of the body along the base of the dorsal fin. Other common names they are known by are Spot-Finned Spiny Eel, Peacock Spiny Eel, Striped Peacock Eel, and Siamese Spiny Eel.
Although not considered to be true eels, the body shapes of all members of the spiny eel family, Mastacembelidae, are definitely eel-like. The Peacock Eel has an elongated, but rather thick body and a pointed snout. This is an aquarium eel that doesnÃÂÃÂ¢ÃÂÃÂÃÂÃÂt get too big, reaching just under a foot (30 cm) in length. Juveniles can be kept in about a 20 gallon tank, but larger specimens will need a bigger area. Adults will need a tank that is 36 inches in length and about 35 gallons.

Peacock Spiny Eel is very hardy and commonly available. It makes a great starter fish for first time spiny eel keepers. It is generally a willing feeder and readily adapts to aquarium life. It is also relatively small, with its maximum adult size being just under a foot long. As it is nocturnal you may not always see it though. It will usually hide during the daytime by burying itself in the substrate.
Peacock Eels are peaceful fish that can be kept in a community tank with larger fish. As you can see from the photo above where this adult specimen is housed with a Jack Dempsey cichlid, they are great with a variety of tank mates. Unlike many of the spiny eels, this species will also get along well with others of its own kind as long as they are of a similar size.
