Thanks everyone, I'm finally figuring out how to take some decent pics
First JFK_Jr : The camera is a simple Kodak Easyshare LS743. It's actually a pretty basic camera. I use a tripod and it also has a 'macro' mode for close shot then I clean the glass inside and out then start taking picutres. I do fool with the cameras exposure compensation a bit but other than that I don't do much.
32Bit_Fish: When I do a water change it is 30-40% I use RO water and Oceanic or Reef Crystals salt.
As far as picking out live stock I have two suggestions, 1) Patience: wait to buy healthy livestock don't buy marginal looking live stock. 2) Ask the LFS to hold them for you for a few days to make sure they are healthy, a good LFS would be willing to do that for you, they should be holding them fora few days anyway to make sure they are healthy.
As far as telling what is a good fish, I'd just watch the fish in the tank for a while. If anyone seems to be acting odd then there may be trouble. If they is a dead fish in the tank, then in my opinion, NO NO NO NO buying any of those fish! Who knows why that fish has died.
Anyway again patience is the key. You will be 100 times happier if you wait and buy healthy fish than if you buy unhealthy fish now.
Well I have to get to work so I better be off, feel free to ask any other questions.
