i can't see the pics so i can't comment on that. but i did see that you said you have extremely bright lighting in your tank. Why are you using such a high iso? higher iso's are usually used for lower light situations. typically you can get away with 100 iso = much better quality and better suited for high light situations and at the most I wouldn't be using more then iso 400. I wish i could see the pics, but they are blocked here at work. Will the lens not pull in enough light at lower iso's? See if you can take some pics at 200 iso at the same shutters speeds you tried above. I'm just curious to the outcome. If you can use a lower iso you will have less noise and typically a better pic. a tripod is a must for sure.
