So i was in my garage, and came across a 10 gallon fish tank and decided i would like some fish, so i went out a bought all the necessary equipment it lacked. I set up the tank and let it sit for a couple of days, then proceeded to go out and buy some fish. My tank has no heater, and seems to stay about 72 degrees. At first I bought some tiger barbs because i liked them, got them home, but after some research i decided i did not have the room to keep them happy seeing as they are schooling fish and semi aggresive. So i returned them and ended up getting one zebra danio and two black skirt tetras. In about a week i plan to add some more but i would like some suggestions on some interesting fish that will live well in the habitat im providing. Probably no more than two or three more small fish will work well. Basically i want some color and activity in my tank, selection seems limited but maybe im just not looking in the right places.
