My betta, Zach, who I got yesterday, made a bubble nest! I saw him adding a couple bubbles. However, it seems quite extensive. There seems to be a main nest, but bubbles spread all around. Is just the main part the nest or did he make all those bubbles? The main part is what I saw him adding bubbles to. His tank is known for making bubbles but I got all the bubbles off. Usually the bubbles the tank make aren't by the surface like that.
