Hello. I was wondering if anyone could please give me some advice or Dos and DONTs for feeding. I was told Spinach is not a good idea to feed them--is this true? I bought a cricket feeder but how do I gut load the crickets? Also, what are fruits and veggies that should not be fed to them? Last question, do I fill the feeding dish once a day and leave it there or only set it in there for a period of time then take it out? Didn't know if food could or should be left for them to freely eat throughout the day. Thanks for the tips. I'm new to all this.
