Last night, my parents took me to the aquarium store to get a pet fish because I got good grades this year. The person helping me recommended a betta and said they needed a 5 gallon tank. He also gave me some stress coat, fish food, a internal filter, a 50 watt heater, some Tetra Safe Start Plus, a master test kit, and some sand. I wanted some plant's and some rocks/driftwood but my parents said only if the fish survives 1 month. I didn't understand much of the what the employee was telling me although he sounded pretty knowledgeable. What do I do with the stuff my parents bought me?
