Ok, umm...I have 3 Bettas, and I have NEVER seen this happening, what is it? What do I need for them to make one?
Lexi_Lover, another thing is they can't be in a tank or anything with a filter running or it will just destroy the nest as they try to make it. Often when I am at the pet store, the bettas have little bubble nests even in their cups they are being sold in. My past bettas never built one as big as Rilo's, but I never did the cup thing or had any females around. They often made little bubble nests in the corner of their bowl.

I may just go betta shopping soon
