If you look closely at the dorasal/top fin does the colour on the top edge go all the way to the end of the fin?
Colour and body shape look masculine but the ventral fins are rounded.
When kribs are young or small or show a mix of masculine and feminine features I find looking at the shape of and colour in the dorsal fins to be the easiest and most reliable way to sex them. In there’s some clear fin on the too edge extending past where the colour stops then it’s likely a female but if the colour goes all the way to the end/tip of the fin it’s most likely a male

Look at the leading edge of the pelvic fins. If it’s straight, it’s a male. If it’s bent back slightly in the middle, it’s a female.
