I bought my albino in May.. he was a VERY tiny froglet.. he is a little over 3 inches long now and does have nuptial pads so I know he is male. Probably need to wait a year to know exactly how big they will get though.

I picked up my wild type ACF a month later perhaps (the one shown in the picture)? He was a bit smaller than my albino.. I want to say they're around the same size now but I've not noticed any nuptial pads so I'm thinking it's a female.
