I got a 5 gallon tank that I divided and put Galaxy and Kryptonite in. They're out of their little 1.5 gallon tanks now!~ Also got a $25 dollar petco giftcard.
I actually bought my friend a fish tank, too. :3 He loves animals, doesn't have a lot of money, and can't have any animals bigger than a foot long in his house due to restrictions his landlord put down on the house. So for Christmas I bought him a 2.5 gallon tank with gravel, a few silk plants, betta food and water conditioner, and I sent him $20 for the fish itself and anything else he wants for the tank. I figured a betta would be an entertaining enough animal for him, especially since they're pretty low maintenance, his younger brothers and sisters won't complain that I didn't get them anything because a fish is kind of a share-able present, and a betta wont push the landlords restrictions at all. It hasn't arrived at his house yet, but I hope he likes it, haha.
