Care
Hawaiian Garden Eels require a deep sand bed to burrow and establish their territory. They are shy and may hide if the aquarium is too busy or if there are aggressive tank mates. Feeding can be challenging as they prefer live foods like copepods, brine shrimp, and other small planktonic organisms. A well-established tank with a refugium can help sustain a population of live food for these eels.
Reproduction
In the wild, Hawaiian Garden Eels are known to form colonies with each individual maintaining its own burrow. Reproduction involves a unique dance where males and females rise from their burrows to release gametes into the water column. In the aquarium, breeding is rare and not well documented.
Habitat
Native to the Hawaiian Islands, these eels are typically found in sandy areas adjacent to reefs at depths ranging from 7 to 45 meters. They prefer areas with moderate to strong currents which aid in their planktonic feeding habits.
