Whats it to ya?
The overlapping shell of the adult isopod can get lodged and caught. Its pretty hard regardless... pill bugs can be either isopods or compact millipedes. Its really had to tell the two apart. Dont feed millipedes usually. They all are slow moving so they are well defended with hydrogen cyanide, fouling hairs, armor as in the case of the pill bugs, or some odd secretion that paralyzes spiders and ants. One in the woods has one secretion so sticky that anything small that touches it gets fouled with debris and dies. Soft young white woodlouse are great but they disappear real quick into the substrate, useless caught quickly. My brown and green anoles rejected adults...
Use a thermometer and measure the hottest parts of the cage to see if the basking area is the right temperature. Just because its the warmest spot does not mean its warm enough. Better safe than sorry!
I think your lizard might be a female. It looks identical to my brown anole that i had,a nd it was a female. The red head and stripe are exactly the same.
