Snowflake eel In reef tank, good or bad?

[monza]

They don't really jump they explore, sticking their head out of the tank looking and pushing up, seeing what's out there. They also go into over flows swim up returns basically anywhere they can and places you'd think they could not possibly go. Whatcan I'm pretty amazed you've had none escape, that's great, I have found snowflakes a little less on the exploring side, maybe that's it.
