Collection Reduction

In order to focus on my Brazilian boa breeding ambitions more seriously, I’ve decided to reduce my tarantula collection. I found a fellow enthusiast on Craig’s List who was happy to have all the individuals I’d tagged for re-homing.

I’m disappointed to see the spiders go, but the boas are a larger priority. Maybe I will be more inclined to keep up with this blog with a smaller collection. Ha! More likely, this will become a blog about my pets in general. Oh well. I had good intentions when I started. =P

Featherleg Baboon [003] June 2014 Update

I never see Mr. Nugs unless I tear out his entire hide. Up to this point, I’ve kept him on coco-fiber with a fiber hide. Now, I am experimenting with this pine hide that used to belong to my boas before it was accidentally snapped in two. I have heard from other hobbyists that it is toxic, but I am not convinced. I think it may be one of those things that nobody knows, nobody wants to risk, and nobody will advocate kind of things. You know, like how we used to think that keeping tarantula cages bone-dry would kill them? Read More →

Tarantula Profile: Stromatopelma sp.

Maximum Size

  • Females can reach up to 13 – 18 cm / 5 – 7 inches.
  • Fast growth rate.


  • Reclusive, will remain hidden until it detects a disturbance. 


  • Proactively Defensive (Aggressive), will go out of its way to fend you off, teleports, and bites without hesitation.


  • Old World (West Africa) Arboreal, but also digs significant tunnels.
  • Thrives at warmer temperatures, but tolerates domestic climates.
  • Thrives with some humidity if fed sparingly, otherwise substrate can be kept bone-dry if consistent water and food are provided.

Hide Construction

  • While juveniles prefer to burrow and are extremely reclusive, subadults and older will appreciate a more vertical space. Hides that provide maximum darkness are ideal.

Featherleg Baboon [003] Feb2014 Monthly Update

I still haven’t witnessed the legendary crazy-ass-aggression that is the trademark of this species. My assumption is that they grow into it, but at about an inch, my cobalt blue already displays her nasty attitude… Mr. Nugs is almost 3 inches… ?

Anyway, I swapped out his enclosure with Romeo’s 1 gal container, so that Mr. Nugs had the larger one. I don’t want to do any more transfers, so this is his permanent home.

This rehouse went very smoothly. I carefully pulled out all the decor in his previous home, leaving only his log, where he was hiding. Then, gently lifted it out and placed it inside the new cage. I closed it up, and through the grated cage top, prodded him out of his log. He ran right to the new coco-fiber hide, so I opened the access door and lifted out his old hide.

Acquired: Featherleg Baboon [Mr. Nugs 003]

My Stromatopelma calceatum is a trophy tarantula. Ever terrified of the species, I realized I would never be able to keep the dangerous spiders unless I actually brought one home, so that’s exactly what I did.

I wanted experience with a Strom as a badge of honor, and honestly because they’re bad ass. I hoped to God this particular specimen would turn out to be male, lessening my term of commitment to him. Not only that, but the males are prettier, I think.

As the 3rd addition to my revived collection, Mr. Nugs came home on November 11, 2013 at about 1.75 inches.

Molt (1): December 16, 2013 @ 35 days from acquisition
2.2 inches

Molt(2): January 23, 2014 @ 38 days from previous molt
2.8 inches, probably male from molt examination

The day he came home.
