For a T 5 approx one year I recommend a month prior to and depending on the screen will determine placement and distance for the fixture-- for a T 8 it needs to be inside the tank w/ a distance of 6-8 inches and replacement every 6 months I recommend 5 --- your UVB is extremely important for the over all health and behavior of the dragon -- it help the dragon absorb the calcium it is ingesting - if you do not have a UVB your dragon will die a slow and painful death -- it prevents MBD which is a horrible disease -- please google it and look at the pictures
Yes -- he will not eat w/out uvb- he cannot absorb the calcium w/ out it and it has to be proper uvb and correctly pleased an distanced- a screen blocks 30 % of the rays
Yes those are great bulb along w/ the Arcadia 12% -- best on the market at this time -- they will interchange w/ your fixture -- and they need to be properly placed for your screen -- and properly distanced -- if you need help w/ that please ask I will help you
She looks good from the pic I can see of her -- as long as shes basking pooping active and eating she is good - if she stops eating becomes lethargic quits pooping and I mean stops they will go long periods of time w/ out pooping then there could be a problem -- ex impacted is a good example -- temps need to be kept good so she can start digestion and good UVB are what keeps dragons healthy along w/ a good diet - google MBD and you can read up more about it -- it effects dragons in different ways like deformed jaws - deformed spines feet legs etc -- pet store employees need to be trained on this stuff if they are going to sell these animals and they are not --- its rare you find one of those people working in a pet store --- most have not a clue as to what they are talking about -- like selling colored bulbs -- those are a big no no as the colored lights can cause long term eye damage -- it distorts their vision - dragons have better eye sight than we do so certain UVB and basking bulbs as well can mess w/ the eye sight
