thanks for the replys and the nom guys!
Here is how we took the pic....
Because he is so agressive and always thrashing around the tank when we came near we had to find out a way to get him to swim past the camera, so what i did was put my hand on the left side of the tank witch ment he swam over and started to bite the window and attack me while i was doing this i got my phone ready at the spot, then my g/f nici put her hand in the tank on the right side of the tank and straight away he swam over to bite her so as he swam past i took the shot! as i took it i thought it would come out crap because i moved the phone but when i seen it i was shocked! it came out really good, i tryed it again about 10 times but it was nothing but blurry.
Once again thanks peeps.
