1) Your lens quality.

2) Taken with the fish at the far end of the tank. Distortion due to tank water and tank glass. (between the subject and your lens).

3) You didn't position 90 degree (shooting position) perpendicular to the tank glass.

Hmm...distortion possible as I juz stayed at 1 position taking all this pics.
Will take note of the 90 degrees issues & see whether it helps, xie xie ni!!!
