Garden eel and seahorse tank

[emmarose101]

I am building an aquarium the dimensions are 20x24x36. We are having the tank so tall in order to provide adequate room for these species. My plans so far are a sand bed of six to eight inches for 2-3 garden eels. I would love to know if anyone has a good idea for a clean up crew with that much sand. There will be live rock and gorgonians in order for the seahorses to latch on to. I was just wondering if anyone could give me some more advice on how to make this tank work. This is about two years of planning finally in action and I want to make the tank perfect because both of these species are extremely delicate.
