Single red bellied piranha tank mates?

[Vesparotax154]

Hi all, first post on here so go easy!
I have 5x red bellied juvenile piranhas but one has always been half the size of the rest, she obviously struggles to compete with food and is struggling now, I have another tank set up which has Oscars, clarias, giant asian upside down catfish, iridescent shark, and a huge featherfin, my question is can a put a single specimen rbp juvenile in this tank, from my 20 years of fish keeping my knowledge sais no but I have seen so many tanks on YouTube ect where people keep single rbps with Oscars ect and have no problems? Thanks in advance

I wouldn't, there will be problems with nipping at the very least.

What size tank are the oscars in?
Sounds like that tank is 300+ to have so many monsters...
