While out in the Pines on Monday, I came upon a wetland bog. As the bottom was hard, I was able to walk around in ankle deep water. I came upon what appears to be bubbles laying on the bottom. I never seen anything like this before. ( See attached two photos). With a little research, could they be Bubble Nest? Wikipedia states: "Dwarf gourami bubble nest made of bubbles floating plants and plant parts which were torn from a Hydrocotyle male". That doesn't tell me much. I did not see any fish, and only a couple frogs. If it was create by a fish, that species should not be in there as for what I read. Any help with this?
