if you can whip her out into the spare tank then when she releases them after week 3 or 4 then put her back in, the eggs hatch after about 3 days so it is the eyes, what she eats will be for the babies btw so its worth offering it every day, like one flake or so
the male is only chaseing her as he doesn't want none receotive females in his territory

but adding another female or 2 will help as each species are best off in trios or more, help with the aggression
