The Communal Project series will document my setup of a Moncentropus balfouri communal, starting with the planning and acquisition of both the enclosure and tarantulas and continuing through as they mature. This is the second installment in the series; the first part is “Communal Project Part 1: An Enclosure by Brooklyn Bugs.”
After a couple of years of research and daydreaming, I will finally be setting up my first communal.
I’ve been fascinated by communals since I first saw photos of H. incei setup on a forum several years ago. I had always known tarantulas to be cannibalistic, so I was intrigued by the idea that a group could live together harmoniously without it turning into a survival of the fattest bloodbath. Since then, I’ve read articles and blogs, watched YouTube videos, and even spoken to a couple keepers who have tried it. I’ve researched the many species said to tolerate a communal living situation, including Poecilotheria species, Heterothele villosella, Neoholothele incei, Pterinochilus murinus, and of course, the Monocentropus balfouri.
Although all of these species have demonstrated the ability to co-habitate with other members of their species without immediately resorting to cannibalism, the level of true “communalism” can vary greatly. Every keeper would love to witness a true tarantula community where members actually benefit from living in close proximity to each other, possibly hunting and even eating together. But the fact is, many of these species are forced to live closely together in the wild due habitat constraints; they don’t naturally prefer it. Therefore, when they are forced to live together in an enclosure, the relationship between the inhabitants more closely resembles a fragile tolerance than a strong communal bond.
As a result, many keepers who have tried to keep communals have found the need to abort the projects upon discovering that their ten lithe specimens had suddenly become five portly ones. With many of the communal setups, cannibalism is a constant threat, and the thought of needlessly loosing often expensive Ts is enough of a deterrent for many keepers. Personally speaking, I love my spiders and pride myself on not having many deaths in my collection. The possibility that by creating a communal I might putting a group at risk of unnecessary death was a tough concept for me to get by.
One species has always stood out for me in the communal list…
One of the species that seemed to demonstrate some legitimate communal tendencies was the Monocentropus balfouri. I had discovered early on that this beautiful tarantula had some of the strongest motherly instincts of any species, and a quick Google search of “M. balfouri mother with slings” brings up some amazing photos of this maternal spider seemingly nurturing its young. This is an animal that keepers have witnessed killing prey to feed its spiderlings, as well as standing guard over them like a protective parent. Hobbyists that have kept this species communally report slings huddling together in the same burrow, even when given space, and feeding on the same prey…together. I have read several accounts by folks who have set up more than one balfouri in an enclosure, and it seems that it doesn’t matter the size of the specimens that are introduced together, they all live quite harmoniously.
After reading several accounts by keepers who had tried communal setups, it seemed that the chance of casualties was low…ridiculously low. I only found one instance where one of a group of about a dozen disappeared, but there was nothing to indicate it didn’t just die a natural death (and not at the fangs of one of its cage mates). Even more promising were the many photos of juveniles and adults living and even feeding together peaceably.
It seemed like if I was going to attempt a communal setup, M. balfouri would be the species to do it with. However, although the prices on these gorgeous Ts have continued to drop over the years, they still run about $60 or so for slings. It would be quite an investment to get one of these going, especially if I wanted to start with more than just a handful. For a little while, it seemed like it would remain a bit of a pipe dream.
Enter Tanya from Fear Not Tarantulas
After my last fantastic experience buying from Fear Not Tarantulas, I got to chatting with Tanya about spiders, the blog, and her breeding projects. It’s been fantastic conversing with someone who is not only knowledgeable, but also thoroughly entrenched in this amazing hobby. During one of our conversations she made an amazing offer; she would hook me up with enough M. balfouri slings to finally start that communal I had been pondering for years. To say I was ecstatic would be an understatement.
The original plan was to start with five or six specimens, so I had to go ahead and set up an enclosure that wouldn’t be too large for the .75-1″ slings, but that would also allow for plenty of room for growth (for more on the enclosure, click here!). Once the enclosure was ready, I gave Tanya the go ahead to ship my tarantulas. I had shared my photos and ideas for the design of the enclosure with Tanya, and when it arrived I explained that it was a little larger than my first idea, but I thought that it would work out well. After texting me with updates on the packing (as well as a photo of the A. amazonica I was was also getting), Tanya informed me that she was actually sending nine M. balfouri. NINE. I was absolutely floored. The extra space would definitely go to good use.
She shipped them promptly and they arrived expertly packed, labelled, and in fantastic shape. As a picture is worth 1000 words, I’m guessing that a video is worth even more. Below is the video of the unpacking along with the rehousing of the nine M. balfouri slings into their new homes (the rehousings start at about 3:32). I will admit to feeling just a bit of apprehension as I started loosing the slings into their new enclosure together. A part of me really worried that they might turn on each other or I might capture friction on camera.
It soon became apparent that my fears were unwarranted as the rehousing went off without a hitch and the nine little slings scuttled to the pre-formed burrows without a single incident of aggression. Even better, when I checked on them later in the day, a few of the slings had actually taken residence in the same burrow.
I’m finding the communal setup utterly fascinating, and I’ve been checking on them constantly to see how they are getting along. So far, so good. As these little guys continue to make this new enclosure their home, I will continue with updates including my observations and video/notes on any behaviors of interest. A few questions I hope to answer are:
- Will the slings all gravitate to one burrow?
- Do they really eat together and without friction?
- Is their any difference in behavior in M. balfouri slings kept communally as apposed to kept individually (I raised three from slings previously)
- Will their ability to get along change as they mature.
Next up…M. Balfouri Communal Project Part 3: First Week’s Observations (and Video of Group Feeding!).

Wow, how exciting, this project is going to be amazing! I had no idea you’d be able to do this, I can’t wait for the updates.

I’m so stoked about this. I’ve always recognized tarantulas to be highly cannibalistic, so to see them live together and feed off the same items without attacking each other just amazes me. My next blog will have a video showing them eating together. 🙂
So awesome,your little colony. Love the little updates on your YouTube channel
Hi, Jane! Thanks so much! This project is proving to be so fascinating. 🙂
what about now ? 😉
The videos were getting much more traffic, so I forgot about the articles. haha
Here is a video that tracks them until now: https://www.youtube.com/watch?v=iRWrd12LjQM&t=8s
