What are some reef safe, small eels that can do well in a 40 gallon tank with a 20 gallon tank, if there are any that is.... Must co-exist with corals, gobies, shrimp and clowns at least.....
 
Not many eels that can be kept with shrimp

On the whole they don't need huge tanks so the 40gallon should be OK

My Pistol shrimp has survived my Snowflake and Whitelip Morays but I think it's just been lucky
 
ive seen snowflakes kept succesfully with both blood shrimp and cleaner shrimp.
 
You generally want to avoid anything from the genus Gymnothorax as these are fish eaters in the wild. Some people have success with snowflake eels in the tanks, but you are always running a risk by keeping prey with its natural predator. I am currently enjoying success with my white ribbon moray, and I dare say the ribbon moray (which appears as black, blue and yellow in its life) would do fine if you can get it feeding (no mean feat).
 
Gymnothorax can usually be kept with cleaner shrimp. I personally favour small members of this genus over Echidna for inclusion in the reef tank, as Echidna usually eat crustaceans. This is probably resulting from the fact I usually only keep "tough" fish that are unlikely to be eaten by a small Gymnothorax without a fight.

In any case, feed them dead foods unless you have no other option. I cannot stress this enough. They will be much less likely to attack living animals if they are fed dead foods and plenty of them.

However, perhaps the best larger muraenid (excluding the ribbon eels) for the reef tank is Gymnomuraena zebra. A gentle, hardy giant, this animal isn't suited for a forty gallon tank but can be kept in tanks of over a hundred gallons. Extra water volume to dilute waste perhaps takes first priority over living space, as they are inactive. Won't eat even the smallest of fish, but can be expected to eat true crabs and shrimp, possibly excluding cleaner shrimp.

A sometimes overlooked issue with inclusion of eels in a reef tank is that they can produce a great deal of bio-load. If one's water changes are kept up (GFO and refugia can also be invaluable) it shouldn't be a problem.
