Monster fish that can breathe air?

[Pyluper]

Are you talking about red bellied piranha. I’ve not heard that piranha can breath air even though Pacu are essentially herbivorous piranha.

I meant Piaractus brachypomus. In my country they called them red-bellied pacu(s).

When i researched the hujeta gars before buying them im sure ive read it somewhere, ill try to find it if i can, ofcourse only one source might be a little Sketchy to take as the ultimate truth wich is on me.

Im only about a year deep into the hobby but have been reading here and other forums for a bit longer, ive learned a lot of things and forget even more lol

Interesting. The fish profile https://www.seriouslyfish.com/species/piaractus-brachypomus/ says that juvenile red bellied pacu indeed mimic red bellied paranha to warn off potential predators. Closely related to tambaque, it is also widely fish farmed as it can tolerate low oxygen water, so I would assume it can also breathe air.

Some commercial fish farms ship goldfish in a sedated, oxygenated, waterless environment. The process usually involves:
Temporarily sedating the fish, Lowering their metabolism by refrigerating them, and packing them in high-oxygen, humid bags with just enough moisture to keep their gills wet.

I've seen live Asian carp sold in fish markets in bucket without water. I am not sure if Asian carp can breathe air directly, but apparently, they can stay alive for hours out of water

I guess that’s one way to save on shipping costs. Hard to believe goldfish can survive in just a humid bag!
