Yes this is true, they are referring to tube UV lights like the Reptisun 10.0 UVB.Special fluroescent bulbs can be found at pet stores, and these will likely run the length of the tank, but be sure they are overlap the basking area. Your bearded dragon should be able to get within 6-8 inches of these lights to benefit from the UV emitted --- is this true???
Nope 6-8 inches isnt all that far but it works well. Im not familiar with the setup youre running as I have a wood viv with sliding glass doors and the UV tube and basking light are fitted inside mine.6-8 inches is not far --- is his tank the issue?? He is in a 40 gallon fish tank, with the lights on top of the black wired lid.....they are the proper holders for lights (attached pictures below)
Sand is not the best substrate for babies (it has impactation risks as well as hygeine issues. But its your choice) , what type of sand are you using? If you feel you want to stay with it normal washed kids playsand is the best. Dont use the "special" types the petstores offer.His tank was sand -- only posts today said to change it.
He now has a sand area and green terrarium liner in 3/4 of the tank....
