Characidae belongs to the Ostariophysi species. The fish have small adipose or connective tissues or fins. The fish have jaws, which include teeth. Characidae also has Weberian small bony structure (Ossicles), which links to the bladder and inner area of the fish's ear. Characidae species tend to arrive from South and Central America; however, a small section of the world may also have these fish, such as Central Africa. You can purchase two types of these fish, i.e. the carnivores, or the omnivorous. Omnivorous will feed from vegetables and/or animals. The carnivores typically feast on meats. You will also find Characidae fish in the predominant herbivorous section. The herbivorous is probably the choice specie you want to avoid, since your aquarium will be destroyed when he finishes nibbling.

For the most part if you choose the Characidae, make sure that you do not include in your tank, smaller fish such as the Angelfish, Fighters, etc. The Characidae tend to use their teeth to gnaw at smaller objects, including other fish. Piranhas? fish are similar to the Characidae species. Piranhas come from South America and freshwater, which these fish also have sharp teeth. The piranhas also have strong jaws, which these jaws are dangerous, just as the jaws of the Characidae species. The fish are predatory species, which attack in large groups. The Characidae tend to attack on their own or sometimes in groups. Yet the jaws and teeth could easily rip apart terrestrial species in a relatively quick time. If you are a beginner, fish collector stay away from this specie, as well as the piranhas.

What they eat?

Characidae enjoy dining on meats, such as worms, etc.

What type of water they enjoy?

Characidae tend to enjoy soft swampy waters. The waters make it easy for breeding, which the fish will lay eggs that will stick to the bottom of the tank. Be aware that Characidae eat their own. Therefore, if the eggs are in the tank don't be surprise if the Characidae devours the youngsters. If you are thinking of Characidae to breed, make sure you learn skills before you purchase the fish.

Serrasalmus Rhombeus

The fish are commonly called Spotted Piranha and White Piranha. The piranhas derived from the Amazon Basins and South America. Piranhas grow up to 10 inches in size. The aquarium fish only grow six inches in size. Piranhas are not ideal for those starting aquariums or fish care. These fish should not habitat with passive fish as well. Piranhas have a deep pressed body. The body has silvery or olive green colors. The piranhas have strong teeth, which they use to devour, or tear apart other creatures, as well as tanks.

The fish rather resemble a bulldog, which they also have a lower jaw line that makes a person feel threatened when approaching the fish. Piranhas are aggressive fish. The fish will dine of large or small fish.

How to net

When using a net it is important that you take extreme precaution. The fish will gnaw at your hand.

Piranhas feed from lean meats and other fishes. The fish are carnivorous, which makes them a showpiece rather than a pet. The upside is piranhas are not picking with water conditions, and the fish will not breed in aquariums. Be aware that if you put two piranhas in the same aquarium, Mary will feast on George or vise versa. In other words, they will eat each other as well. Piranhas include the Red-Breasted and Natterer Piranhas. The Red-Breasted and Natterer Piranhas feast in the same way as the Serrasalmus Rhombeus. Do you need more help?
