I have an almost 15 year old female Brachypelma klaasi that has a "sore" or abscess on the ventral surface of her abdomen. She hasn't molted in at least a couple of years.

I also have a recently matured male B. klaasi that I hoped to breed her with.

Is there anything I can do to help my female? Should I attempt to breed her or should I search for someone to do a breeding loan with him? inbound8280236200363639681.jpg

That looks like a cyst. I'm not sure but I think it'll be okay to breed her since they usually remove it with a molt.

Although I wouldn't breed a female that hasn't molted in years. You should always try to breed a female that has recently molted to lessen the chance of her molting after pairing.

Hard to say. You take a risk either way.

Worst case she doesn't make it through the next molt. Best case she heals up and is fine.

I guess you know the risks either way, right?

(you probably saw this already: )

the question is what is important to you.
Her or her offspring. Either way, you got no guarantees no matter your choice.

Personally i would probably let her molt first.

At this point, not much other then watch feedings.

If abdomen is fat, monitor that. Its definitely abcess.

.

I would not breed a sick tarantula. It could accelerate death. They surely dont need the extra hardships of gravidity. It compares to women having cancer and being pregnant. In a way.

The again, morality is subjective. You good still give it a go. Being a buyer, i sure would like to know that before buying a sling. Though i doubt anyone would disclose this information.

Prepare yourself for this tarantula not getting as far as you would hope.

She isn't and has never been what I'd consider fat. I'm not sure what caused this.

So far, there seems to be no actual TRUE reason. People can say overfeeding might lead to it. But its all speculation. They must all have this in common for such a conclusion.

But, unfortunately, no causes are truely yet identified.

And its a real bummer. Its not a nice feeling, the not knowing what to do.

Perhaps it happens to them just like all animals. They get abcess or tumors, and thats it.

If there was a true cause and solution, we would know. And no one knows. They just say its because of size of abdomen.

At this point, id just prepare for worse case scenario. This is not good breeding stock. Even if it might survive a breeding.

From a human perspective, it looks like it's been there a long time, like a scab!

I had an emilia with something similar looking, but it fresh looking, ie lighter in color, bulging out.. Took her 3-4 molts to heal up. Truthfully no one has a good idea on the board what they are etc. All we advise is to slow down on feeding because we usually see the wall get larger over time, that's what happened to my emilia.

The idea of stressing her out MORE by breeding, I would NEVER do that with a T that has that going on. You could potentially make it worse if she bulks up.

There's a post here a few weeks ago, that links to a EU facebook group that claims they have an idea of what's going on. They are busy hoping peeps send them samples so they can continue their research, examining the tissue etc.

Not sure how to find it look for Theraphosid Research Team maybe, esp on FB for the guys yapping about it.

okay. I will attempt. The recent discussions are about a tarantula species. And nothing about abcess. I need to put diving mask on.

Just so y'all know, she is a beloved pet. I have/had no intention to breed her if the attempt could endanger her. That is why I asked the question.

Also, I'm not in this to make money. I have no desire to produce unhealthy spiderlings to sell to unsuspecting buyers.

That being said, I rarely have a mature male and female of the same species, especially an unrelated pair. I've made a few attempts at breeding other pairs I've had over the years. So far, I've been unsuccessful. I've raised both these spiders from small slings. Her for 15 years and him for 7. Before she developed this malady, I had hoped to have a chance to breed them. It's a beautiful species and I'm disappointed that I won't have the chance to help bring more of them into the world/hobby.

Now does anyone know of someone with a mature female looking for a mature male?

knowing this, i would not judge you for trying. Outcome is, she will die.

you could still try it. Many human mothers would do it anyways.

she could still have a chance. Who are we to decide what is her fate, when we dont even know the cause of illness. Here we all still going on about with our values. Morality. Oh how that is subjective.

Who’s to say they will even pair well.

if i were in this situation, i might still try it. Might. Because if she was wild, she might still have bred.

would you be willing to care for the slings? Imagine if they were to survive and not have cyst.

dont listen to me though.

I wholeheartedly agree with not breeding her. If you read the rules of the classifieds, it explains how to set up an account for the Invertsonals. You can post him there for loan, purchase, trade or gift.

i understand the predicament, especially since having a successful pairing would give you some of her offspring to remember her by when she does eventually pass. (hopefully not anytime soon)

is there any chance it was a drag or fall injury? any rough surfaces in there? or did she have it already after the last molt? In any case breeding her will strech her abdomen as the eggs develop, thats why i personally wouldn't try it, but that doesnt mean that its doomed to fail either.

none of us can know for certain how this will develop, it would be nice if you could give an update on her condition after the next molt, that might teach us something
