i have 9 RBP's in a 50 gallon tank..i bought them march 28th they where cute little dime size fishys...but now im wondering how long does it take them to sexually mature and pair off...and how is the easiest way to breed the piranha when they do pair off...whats the size tank to breed the pair, temp. , and is it a good idea to add water additives?
The only person I knew that had a breeding population had a 1/2+acre pond.

9 rbp in a 50 gallon tank... and about 5" get a bigger tank you should have 3-4 only in 50 gallon max is 4 and about 6-8 inchs if your lucky they should start breeding but thats only if you have a nice habbitat for them and beware when your rbp do breed they will leave al your rbp in a conrner so you might wanna think about getting a bigger tank

All I know is, it isn't going to be easy. I also think you are overstocked and asking for trouble having that many in a tank that size.

First off you will need a much bigger tank. The fact that it is overstocked and too small for p's in the first place will hurt the chances of two p's pairing off.
In addition, most RB's are around 7" before they become sexually mature and start pairing off.
Your best bet would be to get a larger tank and wait, when 2 pair off you may be able to move them back to the 55. Your best bet would be to just siphon out the fertilized eggs and put them in their own tank.

I have RBP too. I have three. I always feed with fishes, death or alive. How old must be piranhas when they start breeding?

i am suprised one has not killed and eaten all the others. try a livestock trough for breeding these can be purchased at most feed stores or tractor supply 200 gallons for about $200. i have one and it makes a great indoor pond

I have bred rbp's by accident. I thought I had Harry and Steve and instead I had Harry and Shirley. lol Clean water quite often. Use a python to help you on that. Even make the water a little warmer when replacing. Feed heavily and keep the light on the tank just on a a few hours a day. Maybe 2 hours. The male will start making the hole in the gravel. If the female doesn't like the hole she will help make it bigger. They will then do their dance, which is interesting to watch. Keep the light off when you see that dance. Within a couple of days hopefully there will be eggs, if not on top of gravel, they will have hatched and you have to siphon them out. Put the babies into a ten gallon and watch them swim and hatch. I just had 15 new rbp's born and still have 7 left over from the first batch. What am I going to do with all these??????????????? :headbang2

I must say, that I had some eggs. The water wasn't changed for a month. There was many plants. I re-built the tank and then I found the eggs at the rock:cry:

I bred a pair by acciedent in a 55 glass tank....Too bad I did not have camera back then....A buddy of mine delivered 5 adults to me a week too early...I was cycling a 100g for them....SO I placed the shoal in a 55...For one week, I monitored everything and did daily water changes....On the 5th day, I had a nest...On the 6th day, I had eggs...Surprised and happy, I placed the remainder of the shoal in the 100g....After all said and done, frequent water changes stimulate the rainy season....DO it, with a lot of feedings(more than usual)....When you see them darken up(to almost black), that's when you know they are the way....When the eggs are layed, let the pair hatch them, this strengthens the bond between them.....AFter the fry are 2-3 days old, siphon them out into a growout....
