How To Make My Male Build A Bubble Nest?

[guppy!]

I had a male I was planning on breeding, and kept him in one of my two breeding tanks, waiting for a bubble nest for six days. Finally last night, I moved him into his old tank, and miraculously, this morning I found a bubble nest in the making ! I moved him into the smaller second breeding tank with a few bubbles in there from the bubble nest he was making. The breeding tank has mostly his normal tank water. Is there a chance he might build a new one in the breeding tank now?

Some males build nests regularly, others don't
You could move the tank with the females in closer to his for a day or so, that might encourage him to build a nest

If you are not conditioning him right now I wouldn't worry about him not building one. If you are, the female should be well visible to him. Put their tanks next to each other. That might spur him into action. He may not build until he can see her in a separate chamber in his tank though.
