I got my new fish a few days ago. I have a boy and a girl. I know you can't put them together until they are ready to breed. So, I have them in a small tank with a divider in the middle, so they can still see each other. Well, two days after I got them, my boy made a bubble nest. It was a fairly large one, too. Eventually, I had to clean out the tank (there was bits of unbeaten food and stuff at the bottom), so I had to destroy the bubble nest. It has been several days now, and he will not build another one. He can still see the girl, but he just won't build a nest. Why won't he? And, os there anything I could do to make him? I really want him to be happy, and I would like to breed them eventually. I appreciate any help. And, I am sorry if someone else has already asked this question. Thanks!
