So both my females are still eating, but in the last couple weeks they both have gained about 300 grams empty weight. I saw 2 locks with one of em but none with the other. Also when my male is with the one he locked up with hes now sitting in the corner of the tub but not trying to court her. Because they are packin on the weight and starting to look like sausages are they gravid and should I keep pairing? Also what should I look for?
