Edmonton today - eel tank mates for my classroom?
 

I'm looking for some tankmates for my classroom tank that has two smaller gymnothorax tile eels. Anyone selling anything neat? (High school..."Nemo" is not neat lol)

Lionfish? Trigger? Wrasse?

Or does anyone have a recommendation for a good livestock shops in Edmonton days? I haven't shopped for fish in Edmonton for a few years.
