I've seen plenty of threads where this occurs. A female is an eating machine until they reach 1000 grams, then they shut down.

I'm just curious how to see how often it occurs . My enchi gal refused a meal yesterday after shedding/pooping. She is also 1031 grams now! I'm not assuming that she's off feed now, but it wouldn't shock me. My albino reached just over 1k grams around October last year, then went off feed for several months. I just thought it was interesting. Who else has experienced the 1k gram fast?
