Whichever of those species you choose, you need to have an aquarium of at least 100 gallons. A group of 5-6 piranhas is very appropriate; however in the event you want them breeding it’s ideal 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 be sure you aren’t looking at them after they’ve been fed. Although having found a man and a female does not automatically mean success, it’s a step along 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 also need to produce the light of half of the aquarium darker than another. Piranhas are hardy fish but it’s an excellent idea to keep the water clear and clean. In their first Amazon River habitat, the rainy season is when most fish predominate. Frequent and larger water changes appear to have an immense influence on the achievement of breeding (since they simulate the rainy season) and are most helpful in getting the piranhas into breeding condition.
If your piranhas lose all their color and then turn almost completely black, they are in breeding condition! Both of them may begin to safeguard a specific place; chasing off other piranhas that come too near. When they begin picking up gravel in their mouths like digging, it usually means they’ve already started the mating procedure. Take care not to disturb your piranhas in this period! The female will release eggs into the pit, and then leave the nest (but may stay close by it). The man is usually responsible for protecting the nest and eggs. The amount of eggs laid varies from 700-4000.
If you’re fortunate enough to have reached this point, then it is time to look after the fry. Be very, very careful when moving the fry, as the parents can be extremely protective and competitive. The fry will 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 license to sell or own a piranha. Make certain to check to find out if any regional restrictions apply before buying your piranhas.
