I have been to the store once. I have 4 fish tanks and I was looking for some specific things for my tanks filters. They happened to have what I needed and gave me a great deal on it.
I looked at the many tanks of fish and my first thoughts was how dirty and filthy the tanks were. But after spending about an hour looking at the fishies and looking carefully, there was no evidence of disease or damage.
Some fish strive for brackish water....
I would agree some of the tanks were a little small for the amount of fish in them.
I will be back many times in the feature as I have been to many pet stores to stock my tanks and they seem to have a collection of fish that I have been looking for that is just not carried at the other pet stores.
