Not sure what it is. It generally is at the top and when we tried to get a piece out (seemed like we would be able to grab it) it sunk down and some is sitting at the bottom now. It is just floating white silky stuff and we just changed the water a few days ago (well, like a 80% change). What could it be? Non of it is on the fish. It is a Male betta in a 10gallon tank, 2 live plants 1 plastic and a few other decorations, no filter and a heater. Just recently got him the tank.
Any guess on what it is? Will a full water change cure it? its not just film at the top that generally appears after awhile.
