I bought 4 firebelly toads online and they arrived the other day. I have two bulbs, plant light and a uvb light. The toads are hiding away from the uvb light. They move to the furthest end of the tank and stay there. Why? I have not read any other thread saying the same thing. Should I have a uva buld instead? What is the difference between the two bulbs besides one letter?

My toads seem fine otherwise, swimming, eating and exploring. Thanks very much, Robin in Maine.
