I recently went petco just to see what they had, I was already on my way to another lfs for a coral. I walked in to find a large saltwater fish section. Much larger than any petcos ive been to. It had its own tank dedicated to corals and a few reef fish. The other tanks for saltwater were responsibly stocked. I walked up to the fish salesman there to find he was a reefer himself!. He would drip acclimate everything in the store, from tangs to snails. I found a kenya tree coral amongst the other corals and it looked really good. I asked him the price because I couldn't find it, and he asked me if I previously cycled my tank and what my ammonia, nitrite and nitrate levels were. He said he really would hesitate selling if they weren't good. My levels were good and after seeinf how much he actually cares about the live stock I decided to buy it. He definitely is responsible and wants the customers tank to thrive and be successful. I was 100% impressed with their fish department at that local petco.
