I do not recommend the 2 remaining stores in Chatham. Last I was there one had more aiptasia then I have ever seen on their rocks and tanks were in poor shape. The other had reduced the salt water section and only carries a few common fish. The closest store would be Sarnia's
The Extreme Aquarium. Next closest would be London, Sealife Central and Big Al's. God I hate living in Blenheim, there is nothing close to me lol. Even Extreme is over an hour for me. Thank god for Ian at Sustainable Marine Canada, he is in London too, but does not have a store front yet. He does come this way and to Windsor a lot and delivers.
