Any and ALL Aquatic turtles need a basking light for heat and a UVB light for shell growth and proper health. A UVB light also helps with digestion of food and fish which will help ensure the happy and healthy turtle. If you can not get a UVB light you have up to 2 weeks before they show any signs of health problems. with out a UVB light they can loose their appetite, have shell and growth deformities and ultimately kidney failure which will lead to a very slow and horrible death. they can not survive with out it and having them near a window will NOT be sufficient due to the fact that the glass filters all UV rays.
If it's a huge tank, has an outstanding filter, and has two or three large basking spots each with UVB light (large means that it can fit all three turtles on it).
I depends
Running a yellow light may result in a traffic violation, as it is typically considered illegal to enter an intersection when the light is yellow.
mid 70's up to 78 i keep my turtles yellow bellied sliders and map turtles outside in pond have a water heater in water. Plus when not sunny basking light and strip light for them.
Without know what the warning light say's, all I can tell you in Yellow means caution.
No, but their happier with it and without it they don't grow to much.
In what area of what continent? Noth America. In Oklahoma Around Carniegie.
their belly is a light coller so when preditors look up the turtle blends with the sun rays coming into the water. when the preditor looks down they see the turtles dark back and think it is only the sand beneith them.
