My girls, when off feed...will sometimes still show a slight interest in eating. Like an unsuccessful strike, or theyll even constrict and kill but still wont eat. Its all good.
Other than ovy, or an illness(RI or something) i dont see any reason to quit pairing.
Ive read if she starts glowing, shell probably continue to glow until ovy. I have two girls glowing right now,ovy should be soon.
