Small tropical fish make good pets

Tropical fish make very good pets. They arte easier to care for and do not require very costly maintenance. There are many small species of tropical fish which are excellent as pets and they also gel well with other fish in the tank. Some of the popular variants are Barbs, Danios, Tetras and Guppies. Barbs thrive better in still water while Danios live better in flowing water. But for all these types of tropical fish, you need to keep your fish tank clean and well aerated. Most of the small tropical fish move at the upper and middle levels of the tank. Keeping a good mix of these small tropical fish species adds great beauty and color to any aquarium.
