I have been keeping frogs and toads for over 50 years and I never thought that amphibians needed special lighting. I learned so much working at the zoo. Some species that I worked with were the Puerto Rican crested toad, Wyoming toad (extinct in the wild), the Panamanian Golden toad, several species of Mantella, reed frogs and other Madagascar species, plus the awesome hellbenders and Japanese giant salamanders. All but the salamanders had UVB lighting or some sort of basking area.

Often times certain species of toads need a dose of vitamin A to prevent Short Tongue Syndrome. Crickets and food items were dusted alternately with calcium and minerals but not every day. Too much is more dangerous than not enough. All this and lighting keeps the amphibians very healthy. Fortunately there are now plenty of articles that will support the use of UVB for some species.
