Just curious about other's experiences... I have some Myriophyllum mattogrossense and a couple of days ago I watched as one of my sae's was apparently going at the growing tip of it. A couple of days later, I find the growing tip not looking too good, and eventually it broke off. I know they will wipe out any moss I put in there, now I see they also like Myriophyllum. What else will they munch on?
