Kuatto,
Which store in Halifax did you visit? Was it Pets Unlimited?
I live in Halifax can attest that there is limited marine livestock, however Aqua Creations carries a nice variety of animals. Where exactly is East River?
If you have a chance pop by and visit the local marine society's forum -
www.masns.ca/forum (Marine Aquarium Society of Nova Scotia). We organize regular monthly group orders from suppliers such as Aquaria Canada and J&L.
