My B. Smithi's crazy behavior

You may remember me from such threads as http://www.tarantulaforum.com/threads/is-this-a-busted-abdomen.9984
I figured I would start a new thread with a less frantic title.

To recap, Felina fell and I was afraid she hurt herself. I enough substrate to leave her about 6" vertically to climb. Here is where the crazy behavior comes in (are there any T's with "normal" behavior?).

First, the bald spot has at least tripled in size, despite her only flicking hair at me once (while I was adding substrate). It is now much larger than before. I assume this is okay unless someone tells me otherwise. Original picture is in previous thread. Here is a picture from today.



Second, she used to do laps around the cage on the glass and had absolutely no problems walking on it. Now she can barely get up it, even though she keeps trying. From what I have read it either means she'll molt soon or that she is really a he and he is old. She just molded maybe 2-3 months ago. Could she be molting again so quickly?
Here she is attempting to walk on the glass:



Third, she is spinning silk all over EVERYTHING. I don't know if it is her way of marking the cage as hers since I cleaned it up and added substrate or what. Maybe she is just stressed from the change and this is her coping mechanism? There is a circle of silk that goes around the outside of the terrarium.

Here is a picture of the enclosure as it is now.



I appreciate any comments on what may be going on with her! I realize that tarantulas tend to act crazy all the time so I'm trying not to read too much into it.

She's in premoult, that's why she's got the bald patch and also why she can't climb as well as before. The webbing is another clue, she's making a comfy mat to moult on.

First, looks like a hair flicking spot, i wouldn't worry about it.

second, she's a ground spider, not a climbing spider, i'd raise the substrate higher to prevent any injuries when she tries to climb, they're not that good at climbing, and worse during premolt.

Third, most likely trip lines to detect prey. All of my Brachy's have the floor of their enclosure covered. No matter where i drop a roach, etc. they're right there at it.

I like the setup though, if that's sand i'd swap it out, lots think that sand is bad for the lungs.

That sounds a lot like my B.Smithi, only he never really had any problems climbing about or did a lot of moving, just webbed up his hide and some substrate and then sat in the depths of his little house (rather like me when I was a teenager :p). I was worried about him, but he was definitely in pre-moult, as he is now upside down and doing his thing!! :D

Bald patch does look a bit darker so @Enn49 probably right about pre moult. Don't forget that if you have added sub....as you can clearly see by the change in colour, all the trip lines and comfy patches once laid down, are now gone so needs to rebuild. That will make the T very busy....I don't think there is anything you have mentioned that would worry me.
My Smithi is rubbish at climbing yet the boheimi is like a little chimp, will scale anything and often hangs from the lid.

As Enn said, it's in premolt. The patch of skin showing is darkening. Normally it would be flesh colored..er, white flesh colored anyway;) And that spider is big enough to sex. As Nicolas said, if you show us a pic of the pedipalps and the first pair of legs we can tell you. As far as climbing, it could be restless due to premolt, or it could be a male looking for females. I think the substrate is probably plenty high, and if you like the sand look you should look into mixing it with clay. Whether or not sand is bad for spiders is debatable (I think it's not, unless it's some kind of very fine, powdery human invention) but that would eliminate any possible concerns about clogging the book lungs. Clay mixed with sand hardens up nicely ;) And looks rather nice.

Well its been a while but I have quite the update!

She finally molted and SHE is DEFINITELY a HE. The pedipalps are now very pointy and he has spurs on the front legs. Not long after he molted he started making sperm webs. It is interesting, he has made a sperm web on 3 of the last 4 Fridays and no other time. I don't know who gave him the calendar but he sure knows when its Friday!

He was sold as a sexed female (he was a gift and I sure didn't know what to look for at the time). So I guess my options are to keep him, send him off to someone with a female, or get my own female. If anyone has a mature female hit me up!

After he molted he was able to walk on the glass for a week or two, but is now back to slipping off the glass. Not sure if that means anything or not...

I got some great video of the molt. When I have some time I'll have to post a video or two.

In the meantime I guess I'll be researching mating and looking for a female for him.

Also, he was sold as a Mexican redknee. Is there any chance that he may be something different? It looks like there are a couple of species in the genus that look similar. Any suggestions?

Restless Male Syndrome!

Good catch, i didn't notice that. I'd agree, smithi has a almost full black carapace, annitha just has the wedge of black.
