First photo is the cactus in question. Second I think is peruvian apple but not sure.

It could be. Or S. queretaroensis? Or not..?
Where are you based, and how did you obtain it? It doesn't seem to be a widely cultivated species, so not likely to be a non-specialist store purchase in many parts of the world.

1. check also St. griseus and St. stellatus
2. OK

I live in San Antonio, TX. I bought it from a man who sells fruit trees and plants he brings up from brownsville and possibly from Mexico. He only told me it was mexican pitaya, but that could still mean one of many different species.

The second one was a large nursery in Corpus Christi, but nobody could tell me the species.

I guess this history and geography makes S. laevigatus vastly more likely than it would be from a source that didn't deal with commercial fruit species near the mexican border.
As ever, flowers / fruits to help the id! Maybe not long to wait for you?

By the way S. stellatus is an old edible fruit in Mexico = (Pitayo, Xoconostle (Mexico), Jonocostle (fruto), Xoconochtli (Mexico), Pitaya, Pitaya de augusto, Tuna (fruto), Pitayo de octubre).

It definitely looks very similar to this from the images I saw. Interesting.
