My petco is amazing. Theres one guy that will tell you to at least get three schooling fish. I know its at least 5 or 6, but he was talking about pure bare minimum. If there's a sick fish theyll treat the whole column not just one tank, and they don't let anyone buy. Once I bought sick fish and I came back next day and the column was closed NFS for treating. They have basic food items and some ich treatment, and water conditioner and bacteria starter. They don't have a massive variety of fish like the houston aquarium warehouse in Stafford (my lfs) and its nice to get to refund fish if dead in 30 days, but theyre usually buried in my yard. Btw can PetCo count as an lfs because then petco would technically be my lfs, but I usually buy most fish from Houston Aquarium Warehouse. Ok thanks 4 reading.
