Petco has a bad reputation on the other fish sites too. Only because they earned it. I have been to the Petco close to me one time and one time only. They had on average four dead fish per tank! I bought four fish and only two made it past the DOA guarantee. I have had good success with Petsmart and walmart. Walmart went way down hill in the last three weeks. Dead fish everywhere and none of them have survived in my tanks. I bought five peacock eels and all have died. They had a shipment of maybe thirty and half were dead the following day. Three days later all but seven were dead. I bought the five that did not have fungus on them. Still they didn't make it. I was there last night and they have dead fish everywhere.
