Absolutely NOT a T. pasiones .
It does look like it could be a "Gold" aureus . Also reminds me a bit of gold mixteco as well. It really is nearly impossible to say unless you know the collection data . Eliioti/maculipinnis is a possibility as well . I try to only get Thorichthys with collection data available anymore . I know this wasn't alot of help . I jsut can't say and be 100% positive on which species it is . I can say very confidently thogh that it is not a pasiones as pasiones gular area is BLACk not r ed as the fish in your 1st picture has
