How long does it take for harlequins to grow to adult size? I bought mine along with black tetras which are fully grown now but the harlequins are still so small?!

are they getting enough food? or are the black tetras hoggin it all. rasboras only get 1.5 maybe 2 inches

Oh, yes they get food i see them eat. I've seen fully grown harlequins but these are much smaller, they are +-2cm. One is slightly bigger than the others because i got him earlier.
I have them for about 4 months now.
