tangtangfish,
welcome to LOL. You've definitely got two
Botia dario there.
B. dario have a very distinctive forehead profile, present in both your fish. Their markings are very variable, but you always get 8 stripes of varying width. Both your fish have the typical baby
dario single stripe on each caudal lobe. As the fish mature, one or two more stripes appear.
Look at these more mature fish here, in this recently created profile, and see the differences.

One thing we've learned here is that out of the ordinary markings should not be assumed to denote another species.
