ID please? I'm wondering if it's Spinipterus acsi or moijiri

Found these in one of the wet lab tanks at ARCOF. I think it's two females maybe in the genus Spinipterus. Maybe

Spinipterus acsi

? I've had

Spinipterus moijiri

before and these look different to me, but it might be that too. They are sold around here.
Cheers, Eric

Here's better photos. The thin one (first photo) looks like Spinipterus moijiri to me. The fatter fish (second and third photos) IDK. Maybe a poorly colored S. moijiri? Or is that S. acsi?

I've never seen acsi in person; for being the 'original' Spinipterus, getting solid info about them is surprisingly difficult.
If I didn't know any better, I'd say the fish in the 3rd, 4th, and 5th pictures were S. moijiri; problem is, I've never seen substantial pattern variation in the few times I've seen moijiri- and the spots look rather "off" to me.
I definitely wouldn't be comfortable calling them moijiri, but I don't know enough about acsi to call them that, either.
Definitely looks like some species of Spinipterus from the fin spines, at least.
Did they provide any collection data?

The whole caudal fin is spotted in S. moijiri and sporadically spotted in S. acsi plus the latter is a bit more brown / generally lower contrasting "colours". Having kept both I know they do change from really quite light colour / high contrast to very low contrast in sparse/light/stress situations versus lots of wood, dim, settled environment.
