bubble nest?

[spiketooth]

When i got home from work my 40 gal have what looks like a bubble nest and its real thick. I have 6 dwarf gouramis 10 guppies some shrimp, otos and some assasin snails. I do run co2 but the bubbles always pop once its hit the outlet. Any thoughts?

Looks very similar to a bubble nest my betta boy made, though it looks much bigger. Hard to tell size from the photo though.

What ever it was, it was gone this morning

Today I finally switched from a hang-on filter to the ViaAqua 750 my tank came with. Now I noticed right away that my Gouramis are what I looks to be spitting at the surface. Could it be trying to make a bubble nest now 90% of the turbulence gone from the hang-on?

So it happened again. Did a little research and gouramis lay eggs and they but the eggs in... heres the kicker a bubble nest. So looks like one of my gourami is trying to have babys. Been trying to figure out which one but no clue.
