To me she looks like the common bristlenose,
Ancistrus cirrhosus. The light saddle across her back is quite characteristic of that species, also, at the baseof the dorsal fin look for a black dot, this is also characteristic of
Ancistrus cirrhosus. the wild caught individuals are common in America, as unlike here in Australia you are allowed to import...lucky bastards!! The wild caught ones will sell for a higher price. F1 means they are the first generation of tank bred bristlenose born to wild parents. I can only assume that its a male in the cave so good luck with spawning them

the albinos are most likely
Ancistrus cirrhosus. Not many bristlenose are known to have the albino morph so that narrows it down quite quickly. Tho it is hard to get a propper ID without a shot from the top.
lovely fish tho!
