I have an African Fat Tailed Gecko. He is one year old and has always been very healthy. He lives in a 10 gallon tank, with eco-bark as his substrate. Temperature in his cage is 85 in the day and 75 at night. I have a thermometer inside his cage. I have a humidity gauge inside too and it's usually about 80%. He has always been a good eater, I have recently switched to feeding him larger crickets that he really loves and seems to have no problems eating. I have recently moved and have started going to anew pet shop to buy his food where they dust his crickets. His crickets have never been dusted before. He is very active, his eyes are clear and his tail is nice and fat. But today I noticed a white deposit on his snout. He shed yesterday so I originally thought it was just a bit of extra skin but it looks like more than that. After doing some research I discovered that this new pet store put way too much calcium on his crickets (they were almost totally white with powder) and I'm now really worried that my poor gecko (Manolo) has overdosed on Calcium. I'm so worried and I don't know what to do. Is there anything I can do to help Manolo?
