Stay away from bugs you are not certain of, or ones known to be toxic, such as fireflies. Feed anoles daily, letting them have as much as they will eat. Prey insects need to be cared for properly to provide the most nutrition for your lizards. If any food is left in the tank, food for the prey MUST be provided. Provide moisture by placing pieces of carrots, apple, orange, etc., in the cricket enclosure.
Dehydration is the biggest cause of cannibalism in insects.
Some anoles may become comfortable with being gently handled. On the whole, however, handling is very stressful to them, and stress will cause them to become ill. Biting, as much as it may hurt you, may be more dangerous for them if you jerk your hand away - this can break their jaws or cause teeth to be ripped out. Since they are primarily wild caught lizards, highly stressed from the capture and the deprivations and often inhumane conditions of the pet trade, they are generally dehydrated, moderately to severely emaciated, and riddled with parasites - just like most reptiles sold in this country every year. A dehydrated reptile will not eat, or will not eat very much, as digestion requires considerable quantities of fluids.
