Piranhas are unique creatures that have gained popularity not just because of their appearance, but also due to the many myths that are told about them. Unfortunately only a few species of piranha have been bred, including Serrasalmus nattereri, S. spilopleura, S. gibbus, S. rhombeus. Another that is considered relatively easy to breed is S. maculatus.
Whichever of these species you choose, you should have an aquarium of at least 100 gallons. A group of 5-6 piranhas is quite appropriate; however in the event you want them breeding it is best to keep a set only, so that there are no other fish to irritate them. To discover a breeding pair pick two adult piranhas, one thick and the other thinner – in many cases thick piranhas represent thinner and females piranhas represent males. Just make sure you are not looking at them after they’ve been fed. Although having found a male and a female doesn’t automatically mean success, it’s a step on the way.
The best temperature is between 73°-83°F. Standard fluorescent bulbs are fine for the light. Piranhas also enjoy some protective cover, and you should also make the light of half of the aquarium darker than the other. Piranhas are hardy fish but it’s a good idea to keep the water clean and clear. In their first Amazon River habitat, the rainy season is when most fish predominate. Frequent and bigger water changes appear to have an immense influence on the success of breeding (since they simulate the rainy season) and are most helpful in getting the piranhas into breeding condition.
When your piranhas lose all their colour and turn almost completely black, they are in breeding condition! Both of them may start to safeguard a certain spot; chasing off other piranhas that come too near. When they start picking up gravel in their mouths like digging, it usually means they have already begun the mating procedure. Be careful not to disturb your piranhas during this time! The female will release eggs into the pit, and then leave the nest (but might stay close by it). The male is usually responsible for protecting the nest and eggs. The amount of eggs laid varies from 700-4000.
If you’re lucky enough to have reached this point, then it’s time to take care of the fry. Be very, very careful when moving the fry, as the parents can be extremely protective and aggressive. The fry will quickly absorb their yolk sacs and you can begin feeding them live baby brine shrimp as food.
1 thing you should be conscious of is the legal troubles. Some states don’t allow the sell or possession of piranhas in any respect. Other states require that you get a permit to sell or own a piranha. Be sure to check to find out if any local restrictions apply before purchasing your piranhas.
