the flash does not harm them....mine do not even flinch when i snap pictures of my tank.....
I knew it would be long between you getting your camera and putting up pics...
Well.....we finally get to see the system...Thanks for putting some pictures up of the tank...Its looking good, fish look nice and healthy...
As said above, get a nice glass clener and get rid of the brown alage over it...look 200% better...Well done
