Eels make an unique addition to the aquarium, drawing the attention of many. They’re fierce teeth and snake-like body evoke respect and bring the mystery and romance of the ocean to your house. KP aquatics offers several eels, ranging from the calmer chain link eel and black edge eel, to the more aggressive green and spotted morays. Chain link eels can be added to aquariums with larger fish. Eels do best with cover to hide under and with a lid to prevent them from jumping out of the aquarium. Eels are very visible, especially at feeding time, but sway out of their holes observing their surroundings most of the day.
