Got a spare 75g tank from a friend was planning to keep red bellied piranhas in it. Would appreciate max info about it and also how many would you recommend in a 75g?
 
Did you check to see if they are legal where you live?

I would say 3 max.
Maybe 5, but you are going to have to be really good with water changes, and there is no guarantee they won’t whittle it down themselves.

A few tips on them:
Its most fun (and cheap) to buy them as babies and watch them grow.
They grow an inch per month until about 6 inches, when they slow down greatly.
Keep them well fed to increase chances of not killing each other or anything else in there.
They will eat just about anything, but a pellet diet is best nutritionally. Most meat should only be a treat as it fouls up the water. You usually want to avoid live feedings.
They destroy plants, real and fake, less likely to attack the latter if well fed.
Prefer lots of cover and low lighting, they are less stressed this way and the lights hurt their eyes. You will see them more with more hiding places, because they feel more secure.
Don’t be afraid of them when cleaning the tank, they won’t bite and will play dead.
Enjoy! :popcorn:

Thanks for the help man. What’s the max size they can grow to and what should I feed them when they are babies? And is keeping them well fed enough from stopping them to kill each other? Also, was planning to do a black water tank, what are your thoughts about it? Do they do better in black water tanks?
 
The full grown average is about 10-12 inches. A small adult would be 8 inches, a big one can hit 13.
I got mine at about an inch and fed it fish flakes until I moved him into is own tank, where I fed it hikari carnivore food sticks. I also gave the occasional brine shrimp, and whatever failed attempts I made at tankmates became lunch.
Usually piranhas aren’t too likely to eat each other unless really hungry or pissed off, so keeping them well fed should be enough to keep them behaved. They will form a hierarchy, and fight/nip at each other. That’s where most of the damage comes, torn fins are going to happen. If one shows signs of weakness, they will attack.
I don’t have any experience with black water, but from what I know, it would be great for them, as it perfectly mimics their natural habitat.
Others probably know more than me. Most of my knowledge comes from research, they are my favorite fish, but I only have one piranha’s worth of experience, so I may not know as much as others.

No worries, you’ve been of great help. Thank you so much!
