Does not look like the picture. I got tarantula substrate for my 2 tarantula’s and it looks exactly like regular dirt that i can dig up from my yard if i go at least 24” down. I spray water in my tank to make it humid and the water just sits on the surface. After 10mins i sprayed again and it did the samething. I poked my finger in and the dirt was dry underneath the surface. I found a bunch of clay clumps.
The last substrate i got for my Caribbean Tarantulas looks WAYYY different from this stuff and absorbed water way better and actually looks like the picture in the bio dudes picture. More of a brown dirt with coconut husk fibers and other stuff. Bio Dudes substrate looks light greyish with clay clumps, little bit of black wood chips and a pinch of some type of fiber

I have already rehoused 6 of my babies (tarantulas) and the Terra Aranea was very easy to work with. The babies ready seem to be happy with it as well. Customer is top notch, will buy from again and again.
