lonesome snowflake eel... tankmate suggestions?

[scrapman]

I have a large snowflakee eel in a 55 gal... it feels lonesome... hiding all the time in its PVC tubing.
Any suggestion for a suitable tankmate likely to invigorate that eel?

Wikipedia knows all....

Compatible tankmates for the snowflake moray eel include other relatively large, aggressive fish, such as lionfish, tangs, triggerfish, wrasses, and possibly even other snowflake moray eels if they are both introduced to the tank at the same time.
