I'm not sure what you're feeding your snowflake, but apparently you haven't read any books/articles on them.......if you don't keep him well fed, expect all of your shrimp and small crabs to disappear in the near future.
Snowflake eels are specialized crustacean feeders with teeth designed to crush shell on shrimp, crabs, etc, although we've found them to prefer squid above all else 10 to 1.
Squid can be found at any Asian or Greek restaraunt as "kalimari".
Here's a photo of our "Lover" (it's A'more') whom we've had for almost 5 years...he's almost 3 feet long.
The crab in the photo is a spider crab with a body the size of a golf ball and a 10" leg span.
