Tarev,
Is it possible that the red one is Echinopsis chamaecereus, 'Peanut Cactus'? I realize the growth habit doesn't appear to be that of a 'Peanut Cactus,' but the 'Rat Tail' cacti I've seen have always bloomed bright pink. I don't want to come across as I'm questioning you, I am just curious because the flower color is throwing me off.
