Yes, given the absence of spots and bent down snout, I'm rather sure this is a capapretum.
The smaller one looks like a capa to me too. I've been wrong before but I'd predict you won't be able to keep its snout intact. The fish is very skittish. Frightens easy and swims full speed until hits something. Often several times on a row.
I am not aware of a single specimen with an intact nose raised in captivity. Maybe someone is.
3"-4" capa is usually ~$100 retail. Fila is 10x or more expensive but has been exceedingly hard to find, almost never available.
