Should I worry?

[Kheyg Kharra]

Bought a pterinochilus murinus(L1-L2?) around 2 weeks ago. Got him a small container for a start and dug a hole for him to hide in (he didn't use it at all). Despite murinus species being burrowers, he would always sit on one of the container's walls and not build webs. When trying to feed he would try to hunt the cricket, but whenever it twitched or moved he would release it and run away. I tried giving him pinned or prekilled ones and feed him myself but it resulted in the same reaction. After a while I came to a conclusion that maybe he will start molting soon and gave him a piece of bark to hide under. Today I noticed that he was laying on his back. I thought that maybe he is actually molting and left him alone, but he is laying on his back for half a day now. He just sprawled out his legs and sometimes wiggles his pedipalps. Should I be worried?

That's weird. Not too sure why this might be, but it is a good sign pedipalps are moving at least. Perhaps increase the humidity of the tank and try not to disturb the spider during this time (I know it's hard not to prod or whatever). Some tarantulas are weird and will spend more time moulting than others. In my experience one of my ts spent about a day lying on its back doing nothing then got on with it and moulted within 2ish hours. To address slings not eating it's very common my first tarantula spent about 1 month not eating upon arrival and is now a subadult female who has a great appetite. Nothing to worry too much about, just keep an eye on it and if it doesn't have any progress there's not that much you can do tbh. Reference this for more info

Thank you for your answer. I hope everything will be alright with it.

Could be anything

Even if container is small, it could have fallen. Doesnt mean its a damaging fall. They act like that for a molt or when they fall. They seem to be more clumsy when molting is approaching. Of course, terrestrials do not have same climbing powers arboreals.

Small instars do better in small containers. Like dram vials or 1inch cubes, when they are under 3/4 inches.

I would not touch it for now. In case its molting.

Keep observing. Even if molting process is long for some tarantulas, its not a forever thing. Even my bigger tarantulas showed some shedding in less then hours.

We could use tarantula photos.

I am assuming L1 L2 means young instar stages for you. So half a day, for nothing happening… thats a long time. Compared to what i experienced with mine anyways.

The fact it did not show feeding responses, that equaled fully eating, especialy with the prekilled, either means its not hungry or premolt, or “insert illness”. If food happened to be to big, it is enough to make tarantula not confident to take it and attempt to shelter itself. The more its attempted, the more the spiderling gets reclusive.

Death curls generaly happen with the ventral to the ground. Of course, the fact there are always exceptions, makes its very hard for anyone to say: I confirm this is happening.

I have two p murinus. When I got them, they were maybe 3/4 or an inch dsl. They had been living in dram vials and had their colors. The dram vials they were in kept them well.

Could be absolutely anything, post pics and maybe a video. P Murinus are heavy webbers so red flag straight away there. Doesn't sound good to me.
