The Sea Life Reefmaster DC 500 or 600 are good all around cameras. I have had good luck with these using ambient lite and the internal flash. There are a good number of features on the camera and the quality is great. Just recently incorporated a micro lens as I like to stalk the little critters. Hope this helps.
Take care and Best Fishes!! `•.¸¸.•´¯`•.¸>
