Who Gives A Fish Forums

I've got a breeding pair of Kribs that spawned around 4-5 days ago, and now the female's belly looks really swollen and bright red again. Every time the male approaches, she curls up and he gets a bit aggressive, flaring his fins. Is it possible they'd spawn again so soon, or am I just seeing things?

I asked the same question at the LFS today and the guy there said they can spawn again even after having new fry. He mentioned they'll actually spawn a lot, but warned that after around the 4th time the female will be really exhausted. I'm wondering, is that when it's best to separate them?
