Thanks Colleen. I usually would see the body of the dead fish so when they vanished, it just make me crazy and try to find them (or their bodies). I have not seen snake here, have not seen bird of prey either. But It could very well be. The sarasa that's gone was a fast one though. I would've thought that the watonai would be eaten first if that were to happen. but I will never know 
I love your picture post card
