Has anyone had success?

  • We are currently upgrading MFK. thanks! -neo

There is another forum where a lot of members breed all kinds of P's. Here's a link to their breeding section. Alot of people there have even bred serrasalmus species.

It's pretty hard to sex piranhas in general, but when they're going to breed they take on a breeding coloration and get darker. Here are some pics of that breeding color change.

Simulating the rain cycle is a good way to breed them. Basically what you do is simulate the same environment you see in the amazon, and it works for most SA fish, not just piranhas. For part of the year you need to simulate a dry season. Most people lower water levels, reduce water changes, increase the tank temp into the 80's, stop regular feeding, and let the tank go a little south. When this happens, they'll get aggressive behavior and may lose some fish. After a certain amount of time (I think about 3 months) you start adding water that is cooler than the tank water by a few degrees. Some people use a spray bar or plant waterer to simulate rain. This increases O2 levels in the water. Then you start doing big water changes with the cooler water, and start feeding a high protein diet. Certain members of your shoal should transition into breeding dress and lay eggs. You should use a breeding mop or water hyacinths (what they is in the wild) to catch the eggs and then remove them to a breeding tank. To my knowledge P's don't raise their young.

Here's a link from that same forum about simulating the dry season:

Good luck, and keep us updated.

This is GREAT info corroberates everything I've every read on breeding Piranha in captivity - This should be a STICKY.

Nice Job!

a lot of times with natts, you don't have to do anything special, they just spawn after they become sexually mature. usually a nice big tank with excellent water quality is required and then a large volume water change using cooler water can spark breeding behavior.

natts are not sexually dimorphic, so sexing them before they spawn is impossible.

if you are planning on having a successful spawn, you need to be prepared well ahead of time with a proper set up for handling the fry, which will consist of at least one decent sized tank or multiple smaller tanks for holding the fry... you will need to have sponge filters for these tanks that have been running in your main tank a few weeks ahead of time to make sure that they have been seeded with bacteria.

once your natts have spawned and you are sure the eggs have been fertilized, fill the fry tank using water from the main tank, then transfer the eggs and the sponge filters over to the fry tank. you will have to maintain excellent water quality in the fry tanks and feed the fry baby brine shrimp... its good to experiment with hatching your own baby brine shrimp ahead of time so that you have the process down before you have fry. as they get bigger, you can switch over to a high quality flake food or small pieces of raw shrimp.

it requires a lot of time and effort if you want to end up successful, but after a few spawns, you should end up with a pretty large amount of baby natts from each spawn.

Once again GREAT info - my hats off to you..............this should be included in the sticky.

thanks homie.



I'm glad to see my efforts are finally being properly appreciated around here! :irked:;):D



oh yeah i almost forgot! barometric pressure. you should time the big water changes to correspond to drops in barometric pressure. It goes down every time it rains.

doesn't seem too active though...

nah MFK is gonna be your most active P site, and the piranha section is hardly popping compared to some others. I guess piranha hobbyists are similar to the fish they keep in that regard.

i would say that p-fury is a lot more active than mfk in regards to piranhas. mfk is a great one stop shop for everything tho, really broadened my horizons on fishkeeping in general... i had never even considered owning some of the fish that people keep here. christ, i even have a tank for clown loaches now, haha, never woulda kept them without seeing some of the clown loach tanks on here.

I think members there are generally more knowledgeable about piranhas there than here, but to me it seems to move slower. More of a specialty site.
