Take the fish back. Most pet stores replace them with the body in hand (or packed up). This is done so people don’t claim (not saying this is your case) that their pet died and is actually alive.
You Have 30 Days To bring the fish back to get in store Credit for the replacement of your fish.
Yes, providing you kept the receipt. Now, I've bought hundreds of dollars worth of Koi for my pond and they started to die. I didn't have my receipt but the employees remembered me, asked for a water sample so they could help me keep my other fish alive. Needless to say, I stuck with goldfish and turtles. Thanks Gaiser Pets, you're still the best!
I've always taken the fish body back to them and I've gotten store credit
