Thank you all for commenting! I really appreciate it!
Yes, I did look up through thick glass walls and water and those fish kept moving in and out of the picture. Probably I should have chosen one of the sharper ones , bt with only one fish.
I really liked the strange perspective of the fish floating above the viewer and realize that the photo is not much worth from a technical point of view or composition.
Looking at the text of "Brain Damage" though, I thought it represented quite well that spongey dizzy feeling of somebody not able of a clear thought!
