If you are shooting from the top of the tank, try a little less of an angle then so you wont get the glare from the lighting. The MH or other lighting you use, will cast a strong reflection on the top of the water so you will have to use trial and error to see what angle will give you the best shot without the glare. They do look a lot better and have more detail than the first posting. It will just take practice and experimenting to get the shots right. The third picture looks the best, hardly any reflection and good detail. I was amazed at how much different the shooting was on an aquarium compared to shooting underwater when I started taking shots of my tank. so keep it up and you will get some great shots..
