Hi DrJekyl MrHyde ~
Good to hear that you removed the mites

Keep checking for awhile as Palor is doing. There might be some chance you missed one, that the mites could have traveled to your cage furniture, or that mite eggs have hatched.
Generally people do not recommend keeping two males housed together in any vivarium under any circumstance. Definitely that could be the source of some of the stress. So you have 2 males and 1 female? Which is the sick one?
Good to hear that you have been feeding them with calcium. Make sure the sick one has a little dish in (her) cage so (she) can lick it whenever as well as dusting (her) food. Hope that you can get the calcium with D3 soon! Should be
phosphorous-free calcium.
Good idea to let all the flyers bask in unfiltered sunlight! That means no glass between the sun rays and the flyer. Glass filters out the beneficial rays. That's why Palor suggests UVB/UVA lighting. Although I only use incandescent lights above my flyers' tanks, the crickets are fed, among other supplements, Fluker's High-Calcium Cricket Feed (which has vitamin D3). Your pet store might have a small container of that to gutload your crickets.
The recommended temperatures and humidity I have for
Ptychozoon kuhli are: 28 C ( 82 F) day, 23 C (74 F) night, 80% humidity. I try, but I don't reach 80% humidity very consistently at all. I will stick the hygrometer in one of the tanks to check this out. Mine never have trouble shedding. In fact, I rarely see them shed.
Maybe MBD, yes. Don't think stress would cause the seizures/trembling.
Good to hear that (she) is shedding and improving with your care. Hopefully you have caught the problem in the nick of time
I did remove the mites...so far so good... at the moment all of them are the same size... but i do have two male house together in a 2footer tank.
Since i got them (2weeks) i have feed them with calcium but without D3..as i cant get cal with D3 as it out of stock at the moment.(will get it ASAP when they have stock)
The 1 gecko that is not doing well...i have separate it and i think it could be some bone disease due to lack of cal or D3.. so i let it bask in the morning sun awhile and hydrate it with lots of water ... it seem much better and it climbing again... and when i handle it .. it can still bite me... seem much better then yesterday. i also notice that it skin is shedding..
i am staying in malaysia temp is ard 27-32 c .
temp should be ok for the flying geckos....But do flying geckos need basking lights or sunlight ?
