The problem you have is with white balance.
Do you have an editing program that allows you to adjust the white balance of your pictures?
If so, you can take a picture under the existing tank lighting but including a photographic gray card in the shot. Remove the card for the next shot, the one you want to keep. When you process the image, use the shot done with the gray card to custom color balance the photo. Use these same setting (provided they were shot in the same light) and your color problems will go away. Auto white balance in most point and shoot digicams cannot handle aquarium lighting very well. Adjusting after the shot is easier.
