Paul,
To Reef Central
Feeding by hand is a No-No because of accidents; eels have poor eye sight, your fingers will smell like bait and look as such.
There is no set time for the eel to begin feeding from a stick. Once it begins to feel comfortable and safe in its environment it will start; have patience.
Snowflakes are not piscivores (fish eaters), to remain healthy and happy feed it crustaceans, shrimp, crab, etc...
Good Luck,
Ed
