Ya i think he is a geyri and ya i just had that 4 foot zoo med layin around from my past beardie. Ya i learned when i had him that the uvbs need replacing every year. When i get paid i will get a new bulb only used it about 6 months then its sat for idk almost a year with no use... so better safe than sorry. As for food. Idk if i will ever feed insects... still deciding been researching a lot. Will just stick to organic spring mix and some veggies and maybe some food pellets also. Now should i dust with calcium or d3 or both and how many times a week?
