Hahaha, Tian-tian hasn't made a bubblenest in months but every once in a while I'll find five bubbles jsut randomly scattered around the tank.
Taco on the other hand LOVES bubblenests. I'm convinced that he's an interior bubblenest designer. He first lined his entire tank in a ring of bubbles, then made a really big one in the center of his tank, then scattered loose bubbles here and there all over the rest of the empty surface. :D He's quite talented, the little bugger!
But Tian-Tian worries me. I don't know why he hasn't made nests in months....
