Was doing some maintenance (aka clearing some FA) when I found this at the edge of the pond. I think this is one of the SMB that the previous owner said was in the pond & I have seen a couple of them swimming about in the last week as well as one today.
Wasn't there the other day and have got plenty of BG and other YOY that don't seem stressed so not sure what happened here. I do have a GBH that visits but no visible signs of injury so I don't think that's it.
Maybe just old age?
Anyway, I pulled it out and put it around the other side of the pond for the other wildlife to have. It'll most likely be gone tomorrow.
I did start up aeration last week and it's been running 3 hours a day for the past several days after a ramp up so perhaps it's tied to that - though I've got no noticeable odors and everyone else seems happy.
