Recently purchased a Firefish Goby from petco. I did not approve of the lady that took our things out of the tank, she threw rocks around and I believe she injured a carpet Nem by throwing a rock at it. She also crushed a Nem by setting it’s rock on top of it. My goby came home with his top fin ripped. He recently went under a rock and shredded his bottom fin (vid below) and I’m worried about him. One of his side fins is also mildly ripped from how he was treated at petco.
