I am in the process of breeding bettas at the moment, but have run into a problem I hav'nt had before. I have bred bettas several times before, but this time the female just won't go to the bubblenest. In the past the longest I have waited for her to do so was about 7-8 hours, but this female has been in there for almost 2 days. My question is, has anyone had this kind of trouble in the past when have bred bettas and did you do anything or just wait it out?
