Hi I am new to the betta breeding world. I have had bettas for a few years now and I recently decided to breed them. I have my breeding tank set up with my male in it, it has been set up for about a week and a half. I have been adding fresh water every so often and taking out any waste. I recently just added the female since she had just finished being conditioned. She was displaying all the necessary signs that she was ready to breed. I have had her in there for a day now under surveillance but I never saw any embraces. Well needless to say I fell asleep on the job and when I woke up there was all this milky white film on the surface. I have no clue what this is and I don't know if I should be concerned or not. The males bubblenest is covered so it is hard for me to see if it has any eggs in it. Is this white stuff just residue from spawning or is it just waste?
