Have Reptile Veterinary Questions? Ask a Reptile Expert.
Do you have a UVB avaialble in the enclosed porch or does it have an open roof?
What is the normal diet?
After the fall did you have him examined by a Herp Vet?
Do you feed any other supplements?
The UVB is filtered by the screen on the porch it also does not penetrate glass, so you really need to set up a UVB light reptisun 10.0 tube type or a Mercury Vapor bulb on the porch. This is very important. They need the UVB all year round for 12-14 hours a day in spring and summer and during the winter 6-8 hours a day. The UVB lights needs to be replaced every 6 months as they do loose potency. I suggest cuttle bones scattered for calcium as they love to chew on them. With it almost being summer the heat may be slowing him down as they do like to burrow when it gets warmer. This care sheet goes over the lighting and the diet especially for finicky eaters. It suggests stinky foods or getting some earth worms or mollusks from the pet supply to see if he will accept them for food: http://www.turtlepuddle.org/american/boxcare.html The fact it has been five weeks since he last ate, I do suggest a Herp Vet visit to rule out an internal issue or parasites. I would be happy to locate a Herp Vet for you with a city and state. I would not wait much longer with him not eating. You can try to add the proper lighting and see if it perks him up, but a Herp Vet visit I believe hands on will give him what he needs to get going again. Joan
I will try to answer your questions to the best of my ability. Stress can be a triggering point for various problems that include parasites as well as nutrional issues. The fall may have created some medical issues, but without some blood work and X rays it is just speculation of what may have happened. As far as the UVB, I have a link where studies have been done on UVB as well as Mercury Vapor Bulbs and if you view the link this give the percentage of loss over periods of time on various bulbs. The people that preformed these tests and recorded the research used a UVB meter and documented all findings here : http://www.beautifuldragons.com/Researchmain.html or this study: http://www.reptilesdownunder.com/images/enclosure/files/lightuvlight.pdf
As far as sunlight, it needs to be direct rays where it metabolizes the calcium in the body. The more direct rays from above increases the potency of the UVB, the better chance that the calcium is metabolized in the body.
I believe that the answers will come from a Herp Vet after some tests are done to deterimine what is actually going on. I cannot diagnose since I cannot see the turtle or handle the turtle. I can speculate on what the problem may be, bu a hands on exam is what will give the definitive answers. Joan
