cud be water condition causing that
or mayb aro not settled yet
mine used to have crossed barbel

must have patience... if the genes of tat fish is good
the shine n development will come in time
like u can see from my pics
it took me more than 1 1/2 yrs for my rtg to look like that
background color has always been blue
the base of my tank is black
white tank treatment most of the time is to show the fishes potential
if u move it to black or blue background. the shine may drop again
your fish and you have given me new hope...not selling...very true wat you say...he will be a champion no matter what...always a campion in my heart...ok in june i will post his pic again...
A new leaf was turned...
