I have a beautiful shimmery blue male halfmoon. The poor baby is dumb as a box of rocks. I introduce him to a real cute female h.m. They run around playing tag. He already as a huge bubble nest, he tries to 包, 换行 around her and he knocks himself out !

when she released some eggs, the male did not collect them and put them in nest. he ate them. He didn't put any in the nest at all. I've seen the females sink to the bottom of tank , but not the males. My male sinks every time, not the female. while he is sinking, she eats the eggs. What to do about this ?
