Grouping of Spotted Garden Eels at a local aquarium

Eels are one of the more fascinating species of fish in the aquarium trade.

Having struck out with the "common" ribbon eels, I turned my attention to the white ribbon eel ( ). It is also a "moray eel" belonging to the Family Muraenidae. This species is equally attractive to me as an aquarist because of its small maximum size (40 inches) and serpentine appearance. I didn't have any luck finding one in the aquarium trade until I stumbled upon one at a local aquarium store. In fact, the store owner had forgotten about the eel, which had been thrown into a live rock holding tank six months previously! I assumed that the eel was healthy and eating in captivity, since it had been alive for such a long time under somewhat questionable conditions. I took it home and placed it by itself in a 12 gallon established quarantine tank. Within one day, it was eating frozen krill from a feeding stick! I had my ribbon eel at last!

This fish is not considered to be a true eel, but like all members of the Mastacembelidae family, known as the Spiny Eels, its body shape is definitely eel-like. It is very cute little fish when it is first acquired. It has an elongated body and a long snout, and is generally about 4 inches long. But be aware that this fish will grow, and could reach close to 3 feet in length. An adult will require a very large aquarium. I really like moray eels and think they would look neat in a reef aquarium.

American Eels are easy to keep in the aquarium as long as they are kept the aquarium. Eels are amazing escape artists. By day, captive eels usually remain buried in the aquarium substrate, or under rocks or other ornaments. By night, they are restlessly active, and will try to eel their way out of the tank or up filter intake tubes, where they risk getting mangled by the filter's impeller blades. Eels are also fond of swimming up the outflow of "bio-wheel"-type filters and into the filter chamber. To prevent escape, the aquarium should be covered with a tight-fitting hood or canopy. If the cover includes a plastic strip that attaches at the rear, make sure that the strip is completely flush with the top of the aquarium and not turned up over tubes, air hoses, and other aquarium items that enter the tank. Cut openings in the plastic strip to fit snugly around tubes and hoses; should any openings remain, plug them with filter floss as if you were adding insulation to a drafty window or door. Fry guards are a must for filter intake tubes. Avoid the use of undergravel filters, since eels will swim down the lift tubes and get trapped under the filter plate. And if it doesn't interfere with tank aesthetics, an added precaution is to lower the water level a few inches from the top. I'm sad to confess that nearly every eel I've kept has foiled my attempts to confine it. Even when I've thoroughly sealed the top of the tank, I will knock something loose during feeding or maintenance, or unintentionally leave the top open after feeding them before I go to bed. Given an opening, an eel will go through it. If an eel does not come out at feeding time, it's best to assume it has escaped. Immediately check under the aquarium stand or cabinet and the surrounding floor area, then expand the search in widening arcs away from the tank. Since eels can travel short distances across land in the wild, it may have traveled across the room. Check under rugs, floor mats, and anything else the eel could hide under. If there is another source of moisture or water in the room, like a drain pipe or a sump pump, check there. If the floor search fails, then turn off the filter and dismantle the tubes while holding them over the aquarium. Check inside filter cartridges as well. These packets often contain trapped food and provide a snug hiding place for thigmotactic eels. As long as they stay in the aquarium, captive eels are exceptionally hardy and long-lived. In Sweden, a captive European Eel named Putte achieved celebrity status for living in various owners' tanks for 88 years. The eel's aquarium hardiness stems from its ability to exploit different habitats and types of food in the wild. As such, eels are not fussy about water conditions and will accept any aquarium fare. It's even possible to keep eels in unfiltered aquaria as long as they are not overcrowded and overfed, and partial water changes are performed occasionally. (Bait dealers and fish mongers are able to keep eels alive for lengthy periods in atrocious conditions.) Once adapted to aquarium life, eels will come out from their burrows as soon as food hits the water. I like feeding my eels live blackworms. I use a turkey baster to squirt the worms directly into the substrate, where the worms live until the eels find them. Eels will also perform a valuable service in the community tank by feeding on dead tankmates. Should a fish carcass get wedged unseen behind a rock, piece of wood, or other decoration, an eel will gladly strip it to the bone before it can foul the water. Given enough food, small yellow eels will usually leave living tankmates of the same size or bigger alone. But as they grow -- and they will grow quickly -- so do their appetites. If their food intake is not increased, they will start picking on other fishes at night, especially other bottom-living fishes, such as darters. When my darters' fins start looking ragged, I know my eels are hungry and not getting enough to eat.Collecting eels is almost as easy as keeping them. Netting elvers or small yellow eels is as easy as spending a few hours with a seine in just about any stream along the Atlantic or Gulf Coasts. Baited minnow traps also attract eels, but only large ones will remain in the trap (where they often gorge on other trapped fishes). Be sure that local regulations allow for the collection of elvers and yellow eels. Occasionally small yellow eels are available at aquarium stores, where I've seen them labeled as the more exotic-sounding "Sargasso eel." Coastal bait shops are also a good source for yellow eels, but they tend to be on the large size and usually available only during striped bass fishing season, which runs from April to December depending on the region.
