Marine Garden Eel (Hass’s Garden Eel)
The Garden Eel, also known as Hass’s Garden Eel, resembles a colony of seagrass. The main body is typically buried in sand and will retreat into the substrate when approached.
It requires a 40-gallon or larger aquarium with at least 6 inches of sand, a gentle water current, and should be kept with non-aggressive tank mates. Minimal decorations are recommended. A tight-fitting lid is essential to prevent escape.
Diet consists of meaty foods and live foods such as freshwater ghost shrimp or small feeder fish.

The Garden Eel is a peaceful addition to my tank. It hides well in the sand and only comes out when handled. I’ve been feeding it ghost shrimp weekly and it’s active during the day. The tank setup was straightforward, and the eel has adapted well after a few weeks.

It’s a unique and calming sight. I kept it in a 55-gallon tank with fine sand and gentle flow. It doesn’t require much attention, just regular feeding. I noticed it stays buried most of the time, which is normal behavior.

After adding the Garden Eel, my tank feels more balanced. It doesn’t compete with other fish and stays hidden in the sand. I feed it small shrimp every other day and it’s thriving.
