hi there so sorry to hear about ur frog. im not 100% about this but i dont think u should use a uv light for frogs, i dont on mine as i heard it dries them out so id maybe take that out (check 1st tho). yeh id defo do as ebony said and use the calcium powder if u do think its a deficiency (tho this should b used anyways). if ur really worried id go see a vet as theyll probably b able to help. hope hes better soon
