Taking over a bubble nest?

[DanMan092]

One of my dwarfs built a bubble nest in the corner of my tank. K cool. Then it broke off (dunno how) and floated and got stuck behind my UV sterilizer intake. So the gourami just kinda ignored it. But then I found out he started to make another one where the old one was. The old one slowly dwindled away. Then I came home and found a DIFFERENT gourami rebuilding the old one, and the other one still making his new one. Funny thing is i'm pretty sure all 3 dwarfs are male!

I gotta get some females to make em happy
