Petco needs to stop carrying saltwater fish. The staff barely has minimal knowledge on the care of such delicate animals. They have animals together in their tanks that eat one another in nature or otherwise cannot peacefully co-exist. The salinity in their tanks is always way too low. The light in the tanks is completely inadequate for the photosynthetic invertebrates they sell, if not sold, said animals die in a few days to a week. Lastly, EVERY time I go to Petco their entire stock of saltwater fish are always infested with White-Spot disease, otherwise known as Ick.
