I know this is an old thread but I figured I’d debunk some of the misinformation here…
But first, Hi! Petco employee here
Petco did previously own LiveAquaria, but sold off several (5ish?) years ago. Currently, LA’s only affiliation with Co is as the vendor for fish bought via Petco.com.
Fun fact- when stores order fish - LA isn’t even an option as a vendor for us! Which leads me to the next part….
Price matching policy has always been for dry goods only, but unfortunately this is not very well communicated within the ranks in most stores. The reason being is that the specific fish you see in our tank came from a vendor other than LiveAquaria. Therefore, the price Petco pays will be different, and obviously there are also other costs involved in getting that fish to the store and into the tank.
Hope this clears up some confusion
