Yeah Nic I know they are more active at night. I just thought there would be a subtle decline if it was motoro. He used to eat like a pig, always active and one night he didn't eat much which I thought was odd and the next day he was on death's door showing signs of curl.
Up until that point he had been normal no change in behaviour or any signs. I work from home most of the time and spend a lot of time watching the rays and always watch for an hour at feeding time so I am sure I would of spotted something.
