Live fish pictures can be very difficult to do. Water blurs subjects and then the subject won't hold still. Blur is my worst enemy. Keep in mind, this fish is almost a foot long in my 55 gallon tank. :-) This was taken through the glass with good lighting. The only thing I did to the shot was use clone brush to add stone to the inside of the cave. There's a hole there which shows the power outlet behind the tank.
