Matt, thank you for the kind words and your article that help launch this endeavor. I don't know if you are aware that someone else wrote a garden eel article for the 2011 Marine & Reef magazine. So it looks like you started a trend. I am very happy with my garden eel setup and I'm glad I decided to go this route.
Yes, initially the garden eels setup shop in the not so deep parts of the sand bed. Over the next couple of weeks they moved around a bit with all but one setting up shop in the deepest(8in) part of the sand bed. I would say that the other one is in about 5 inches of sand and he seems happy there. They also seem to have paired up a bit with 2 sets having paired up to where they are in very close proximity and get along fine. One thing that caught me by surprise is how long it's taken them to really settle in. 2 of them were out and eating from week 1. The rest took about 3 weeks before they were consistently hanging out of the burrow and eating. I'm also surprised how they have taken to flakes and pellets and how they would not eat the PE mysids (too big for them I think).
To be honest I only wanted to end up with about 4 garden eels for the space I allocated but my survival rate far exceeded what others had told me to expect. I ordered 8 total. One was DOA and one magically disappeared but the other 6 seem to be doing really well. I may expand the sand bed by about another square foot to give them a little more room. If you ever write another garden eel article, be sure to mention the unique way they use to go potty. They almost extend completely out of their burrow to were their anus is just out of the burrow and do a little sake to get things flowing in the current. It is really a neat thing to watch. I'll have to capture it on video and post it here if I can catch them in the act.
