As mentioned earlier, the feeding range for a garden eel is restricted to mere inches from its burrow. This presents a unique challenge for the hobbyist looking to provide adequate substance for their Spotted Garden Eels. I have been most successful in creating a gyre-style flow pattern within my tank that steadily runs a gentle current across the surface of the sand. In my particular setup the current climbs up the substrate's slope and across the entire surface of the area occupied by the eels. Note again that the eels will initially move a few times until they find their preferred location and you'll soon discover that this has everything to do with the current and the food in the current. To feed my eels I simply put the food in the path of the pump creating the flow. The food is quickly delivered to where the eels have made their home and as an added advantage of the gyre flow pattern any food missed during the food's first pass will soon make its way back around and this gets repeated several times giving the eels ample opportunities to grab their share of passing morsels. My suggestion would be to play with your circulation pumps to achieve a gentle and properly directed flow and remember that the eels will fine-tune their location so you won't have to fine-tune the flow.
