Edmonton newbie needs help

[Axial Corillite]

Hi Edmonton reefers
I was wondering if someone could help me. My wife's cousin just got
her husband a 50g salt aquarium off some guy and he has no idea how to
set it up, look after it or where to get fish and dry goods from. So....I was
wondering if any of you knowledgable Edmontonians could spare some time just to go over and see what he got and maybe give him some pointers.
