Hi Ahmed,
Another good week. ;)
Yes, these discus are constantly on the move, I was just lucky to video them in one of their rare slow moods to take the second video and try to show the size.
I took the video a little over 10 feet away to minimize as much camera distortion for the best size relationship to the sponge as possible.
I appreciate you taking the time for the compliments. :)
Take care,
Bill
