i have a 1 gallon aquarium all set up and ready for some fish. on the box of the aquarium, it sugests, betta (i already had one and it was way too cold for it), guppies, cory catfish, danio, dwarf gourami, and small barbs. ive been doing some research and i cant figure out which is the most suitable for the conditions. im not sure how cold the water is exactly, but my house is usually between 58-68 degrees F. please help!
