One of my large discus has taken to waking me up in the morning by pushing the glass lid up and banging it down. I was hoping this was an isolated incident, but this has happened every morning at the same time this week. The first time he knocked himself out cold.
My lights have a 3 hour ramp up time, so it's not the lights. I'm never home the same time so it's not that. I do not feed in the morning so it's not that. I'm at a loss
I should add after he does this all is well the rest of the day.
