39
Q

What do sick/stress reptiles often exhibit?

45
Q

What should be considered when placing the secondary heat source in a reptiles’ enclosure?

46
Q

What should you never do with secondary heat sources?

A

Allow direct contact with the reptiles - burns

60
Q

What wavelengths of light are in UVB?

A

290-320nm

61
Q

What does UVB do for reptiles?

A

Required for conversion of Vitamin D3 in the skin
Important for calcium metabolism

62
Q

Why should you replace UVB lights regularly?

A

Efficacy declines over time

63
Q

What is the types of lighting required dependent of?

A

Species
