sounds like she wants to spawn and he's not responding. lol. I had a female betta like that once.
I will be calling the pet store I think to periodically check on the male powder blue that I took back. Both of mine were males. I kept the more aggressive of the two, I was afraid the injured one may be sick as well. But I am very sad that I couldn't just move him to another tank or something.
I hate when these problems arise. I was completely paniced last night when I found mine injured!
