A few weeks ago I got the idea to add something to the terrarium, to complete it! I chose hermit crabs and so far I'm pretty pleased. I have 3 so far and each has it's own unique personality even in the first few days. I've done a bit of research but there's nothing like asking people with experience.
So here's my terrarium set up...the dirt is fir and sphagnum peat moss mix. 100% natural and what not...that's been in there for about a year, and I've been adding small layers periodically. It's about 4 inches deep now, and there's abit of gravel at the bottom aswell.
The plants in there are pothos vine and a dracaena that I'd like to remove since it's over growing the tank alittle. I figured since they're tropical plants they'd be okay for tropical forest loving critters...right? From what I've looked up it seems to be, any other experiences?

here's a pic of the bag of substrate I use...I used it because I had it

Thanks so much for your patience with this hermie newbie!
