Pic would help. Id can be tricky. If its what I'm thinking it might be a "barred" moray. Kind of white with brown stripes? If that then it should stay under 2 foot, with mild temperment. I havnt seen/delt with one in years.

If it is Echidna polyzona then it is a small hardy very easy to care for eel, similar to snowflakes and chainlinks in terms of overall behavior and such. I gave up mine in 2011, but had no issues with it. Standard moray care with this one.
