Hello, all. I have a 120 gallon (48/24/24) freeing up shortly and have been considering getting a big piranha as the new occupant. Thinking about 15 inches or more. I have no interest in feeding live or skeletonizing cows in thirty seconds, etc.; I just like the idea of having a big piranha. I think I would also keep some dithers like Jack Dempseys, as it appears that people have success with doing so. I am looking to get your input on whether I should target a rhom or a piraya. Which is more personable and hardy? Which is more likely to adapt, if previous owners have not already done it, to pellets or homemade gelatin food? I would like an avid feeder, and I do not want a fish that panics when I walk into the room. Aggression at the glass is fine. Thanks.
 
What your describing in the broad sense is a black piranha but they can take years, if not longer, to reach 15 inches.

What I am asking for is input on the question I should buy a 15 inch (or larger) piraya, or a 15 inch (or larger) rhom. I am not growing out a small one.
 
Both are gonna be pricey buy personally I find large pirayas more impressive. The convex head makes them look a lot bigger.

I've worked with a big school of them maybe around 18" and they ate mazuri gel diet just fine.

Also the yellow on the sides is nice.

Ive kept dithers with P. nattereri but one of those fish is a whole different game.

My Nats slowly picked off all the dithers, and finally I was left with some giant danios - which persisted for quite some while, but again, the P's were picking them off.

Lasted maybe 8 months total.

Some very large aquariums keep them in densely planted tanks where they "get along" with other fish by not being able to see them.
 
So, 1 vote for Piraya. I am leaning that way myself. They seem, from what I see online, less aggressive and more relaxed than Rhoms (which often have a callus on their lower lip). I figure with Jack Dempseys they are either tank mates or feeders, not a big loss if they go but I find fish tend to do better with some activity in the tank.
 
Oh wow... I would for sure get the rom if I was you.

Sorry misunderstood the question at first.

Get the Piraya. AquascapeOnline.com has a 14" Piraya for sale if you don't mind coughing up the $1,500 for it.
