Freshwater ID

Sorry, recently posted this in the wrong area.

I'm just getting back into fish and inherited a 20 gal. with two old (close to 5 yr) fish in it, and not sure what kind. They're about 3" long, mostly silver but with red tinges on their fins. One has a black diamond near the tail, the other doesn't. Thanks for any help, sorry for lack of pic.

Think I figured it out. Two buenos aires tetras or one buenos aires and one columbian. They're huge. Probably close to the end of their lifespan. But a lively bunch.

They've done well for 5 years.

They certainly seem hardy!
