Peacock Eel (Macrognathus siamensis)
Also known as the Peacock Eel. These eels are fun to watch while they swim around the tank and make a great addition to your fish tanks!
They are the smallest species of the spiny eel family and max out at around 14".
They have cool movements and add a bit of exotic-ness to any freshwater tank. They are about 4-6" or so in size at the moment.
