PETCO is a chain pet store found all over the twin cities and beyond. PETCO has been very good to me in terms of the quaility of their fish. I bought my work fish, Ralph, from Petco and he has been a good, healty fish. PETCO has a variety of different fish, and they seem to take very good care of them. They also have about every type of fish accessories known to man! They had so many aquariums and fish bowls. PETCO seems to be much better in terms of their fish's health and also, they seem to have more accessories.
