Could be from bad readings of the hydrometer. Try to get all of the air bubbles out. Very hard to say with the little information you've provided though. Have you had your water tested recently by the store? I recommend you get your own test kit.
Different fish are sensitive to different things, especially when still acclimating to a new tank. I would review your acclimation procedures and get real numbers as to water quality to share with us. Don't add any more fish until you think you have the situation stabilized. We all lose occasional live stock for forces beyond our control, such as poor collection practices.
Did you cycle the tank? How are you acclimating the livestock to the setup? Inverts need a long drip acclimation time or they can be 'shocked' and cause death due to differing parameters from tank a to tank b.
