I definitely didn't force the probe, actaully probably could have gone a little further but by 6 or 7 scales after probbing TWICE I knew it wasn't a female... oh well... we didn't plan to start breeding for a little bit anyways so we still have some time to get some females together. At least all the boys are up to weight! =)

The pastel is almost 2100 grams so I'd rather not pop him. I like the probes so much better.
