I spent Monday driving around with a friend of mine to about 20 fish/pet stores looking for browsing, comparing prices, etc (He's starting to set up a dwarf cichlid tank). I went to at least 10 places that I had never been to before. Mot of them tiny mom & pop stores.
One had the most knowledgeable salespeople I've even seen at a store. Actually being honest with customers ready to shell out big bucks for fish though he hadn't cycled the tank and didn't have the right set up for the cichlids he was looking at. The clerk asked him how old the tank was, whether it had been cycled, and then explained the whole process to the guy and ended up selling him 3 zebra danios to cycle the tank with. How refreshing.
Then I go to the next store on the list. A mom & pop ALL-Fish store. Every single tank in the store was diseased, every one of them had yellowish-brown water (no driftwood or peat, just waste), every tank overrun with hair algae. These tanks had obviously been left in these horrible conditons for quite some time. Literally, for every sick (and they were all sick) fish swimming in the tanks, there were 2 dead ones rolling around the bottom of stuck to the filter intake. I was shocked. I started asking questions and the guy I was talking to turned out to be the owner. When I asked him why the conditions were so bad and if he was treating the tanks (very politely), he started screaming at me & threw me out of the shop. Now how can a place like that stay in business?
