This is a rescue. She was so stressed when I found her and I was worried she was holding fry due to the conditions she was in. So i adopted her. She seems quite calm now and generally happy, however she has chewed food just to spit it out and i noticed her flash her belly against the gravel. I have had platy pregnancies but have not had one ever get this large. Water parameters are ammonia 0 nitrite 0 nitrate 2.5 ish. Is thia behavior typical of pregnancy?
