Hello! Just some questions about Krib pairs. I bought a male and female Krib from my LFS which settled in quite nicely in my 60L. The male was slightly smaller than the female which I was a bit concerned about but they were acting fine together in the LFS and initially in their new home. That was until I fed them and the female decided to take a disliking to my male. She would chase him whenever she saw him and would nip at him. I was considering taking them back to my LFS. Then one day, starting off with her still chasing him, they suddenly were ok with each other and started shaking at each other. The female's stomach turned the characteristic red and now they're always with eachother. It seems to me that they've paired now but I may be wrong.

My question is: is it normal for a pair to happen were the male is smaller than the female? I know females are meant to always want large males. Also, what made her suddenly change her mind?
