See if it makes a diff to brace yourself & the camera against something. To do good close-ups you have to be perfectly still---(I'm still learning to do better ones too)
Mine just looked at the frozen daphnia and looked at me as if to say "what you seriously think were gonna eat that bring on the live stuff" then again even my adults wont eat it either! Then again they dont have much choice in eating the dry food as thats all they get now on a morning and then they have live for their supper.
Thanks for your help I doubt they would have made it this far if it wasnt for you guys!
