Looks like its gonna be some good substrate for my curly hair tarantula i even ordered some springtails to help keep the enclosure clean.
Love the packaging, love the tropical mix and will order more in the future 🥰
So just got the megamix. My first impression is that soil is a wonderful organic mix. You can see, smell and feel the difference in this substrate compared to any others ive used. I really love that a complete list of ingredients is given. I fully believe this will be a great mix for my bioactive enclosure in the long run.
The product is great! I love the substrate and will be ordering more.

from 396 reviewsThank you guys so much for my new Spider! You guys updated me weekly on weather conditions and when it was finally safe to ship! You guys packed it very nicely and I was very impressed with how professional everything looked when unboxing it! And also purple is my favorite color haha. The spider was very calm when I opened it up and it actually hopped into the enclosure I had prepared for it from the thick paper towel it was wrapped in 😊… you guys deserve higher than a 5 star rating seriously! Very professional business and I am beyond impressed and satisfied ⭐️⭐️⭐️⭐️⭐️
This beautiful sling came to me with a healthy abdomen size and a spunky personality. We are already doing shenanigans together. He loves his cork hide and started webbing it up and digging a bit on his first night with me, and I love seeing what he's done each day. Happy to have my 2nd H. pulchripes, he did not disappoint! The handling was incidental, do not recommend with this species, but I got such a great shot of how gorgeous he is. Definitely shenanigans happening around here. :)
This little booger is adorable.Eating good moving good everything good
It was a good buy I just couldn’t pick it up that’s my fault. Thank you
Appreciate the consideration they have for these animals to ensure they arrive alive & safe during the colder seasons. The constant communication with Jess & extremely accessible if I had any questions. My C. Versicolor arrive yesterday, took a cricket & so far so good! Thank you all so much!
Thanks so much they are doing so well think they are going to molt soon
The tarantula was held until the weather was safe for shipping. It arrived on time once shipped and is doing great. Great communication throughout.
Beautiful spider. Pictures don’t do it justice. Great sellers can’t say enough good things. Very great on communication and shipping updates.
I received my C. Versi sling in great condition. It was packed well, and the sling looked healthy and ate right away. They were also very easy to communicate with even though I ordered right after the holidays!
Top notch. Shipping during the winter is tricky and my tarantulas arrived safe and sound.
Beautiful healthy baby spider ! Very happy with the new addition.
Well packed, amazing customer service, and really healthy sling. Thanks will buy again and highly recommend.
The little C Versicolor sling I got from Marshall Arachnids is perfect! We had some unseasonably cold weather which delayed shipping a bit for safety of the spider. They were very communicative throughout the whole process. Finally got beautiful blue baby last week. Very healthy! Packaged perfectly. It has already taken to the new enclosure and started to web it up. Good appetite. Can’t wait to watch this little one grow and will absolutely shop with Marshall Arachnids again.
