These fish originate in South America and Africa. They are very
suitable fish for any aquarium, and their sizes vary. Tetras are probably the most famous of this
family, Neon Tetras are always popular. Don't forget about the Piranha,
a fearsome fish with a taste for flesh

 Silver Dollar (Metynnis argenteus): Quite a popular fish. Peaceful, and is a schooler. Although you can only see the fins with a few
spots, this fish can get quite a few "pimples" on their body. Small, black spots so dont worry
straight away!!

 Serpea Tetra (): This is a very colourful Tetra, and
I have 4 of these in one of my aquariums. They are a very fast swimming
fish, very hard to catch with a net. They can behave aggresively to
a weaker fish of there species when there is insufficient food.

brown, with a black rim across the body, which has many spots. It can also "fly"
above the water, by flapping its pectoral fins, so make sure that the
cover is closed.

Red Piranha (Serrasalmus nattereri): The "Jaws" of the freshwater tropical aquarium, I'm
sure that everyone has heard of this fish. Its teeth-filled mouth
and aggresive nature makes it suitable only for a piranha only tank.
