I have a new addiction, so I have been to a few Sydney aquarium shops in the recent past. I was beginning to think that the fish world was populated by weirdos with bad housekeeping skills. But today I changed my mind. I went to Aquaristic near Green Square Station and found a place of clean beauty with normal, charming and well groomed people. (Lots of staff - what a treat to be so well taken care of!) As Anthony Rae said so eloquently above, this is a space where the art and the science of the hobby can be explored. I will be back. Brace yourselves.
