Fin, Fur and Feather, a pet shop in Qunicy, MA, is going out of business
They have deco ships, plastic and silk plants, food, tank dividers and aquarium set-ups still available. I bought a Penn-Plax divider for 50%
off on Wednesday of this week (mid-february 2011).
They are a small store, and their selection is not huge. I would call first to see if they have what you are looking for, on discount.
A web search provided their address and phone number:
503 Washington St, Quincy, MA 02169
NOTE: This is not a reccomendation of Fin, Fur and Feather in Quincy or their sister store in Hanover, MA (which appears to be staying open at this time). I am merely noting the closing of the Quincy store for those who can use the sale information.
