Male was born August 3rd, 2015...Female was born October 21st 2016...so ur right on the money for their ages. Girl i kept from July16 hasent marbled much yet either at 9 months so we have a while yet to wait. Seems to come in alot at 1-1.5yrs. My girl has been changing alot lately by the day tho. Gets real pixelated for a day or two, then new brighter colors fill in the light patches.

male at 9 months has already colored up alot more like ur 20 month old. His has to be the fastest developing one outta 9 so far. Def. been nice to keep track of these later batches. My 1st 2 have gone into the woodwork somewhere lol...
