What did the vet say about Akinna's tail?
***When you pulled off the skin from the tail tip, did it seem like stuck shed or was it pink/raw underneath? Maybe infection set in?
***Can you get some very small hornworms? Perhaps Akinna will eat those while taking the Flagyl?
***77 F overall fine at night
***Good taking the temp
inside the warm dry cave where the heat is naturally trapped

***Best to have 3 hides: warm dry, warm moist, cool dry. Warm moist hide assists not only in shedding but also in keeping your leo hydrated.
***Air temp on warm end too cool at 77 F. Consider getting an overhead dome and bulb for additional air heat during the day. Heat drops off rapidly as it rises. Leos need warm air too.
***Rheostat's will not shut off when the temperature goes too high...like over 93F. Thermostats will turn off. Thermostats take some of the worry out of heating.
***What did Akinna weigh at the vet?
Gutloading the Feeders versus Feeding the Feeders 24/7
The term gutloading causes some confusion. Feed your feeders a nutritious regular diet all the time to build strong feeder bodies. Then only feed a special GUTLOAD product to the crickets 36-48 hours prior to feeding the crickets to your geckos. T-REX Calcium Plus Food for Crickets is the only proven gutload food as of July 2013. Especially at gutloading time be sure to provide crickets with a damp paper towel for moisture but no fruits or vegetables because the crickets will consume fruits and veggies preferentially over the calcium-enriched diet.
Maybe, top off the crickets by lightly dusting with a multivitamin containing D3/vitamin A acetate no more than 1x weekly and according to the directions on the container.
