HCA: Hermit Crab Association

Hi everyone. I am currently working on My new hermit crab tank.
I would love to put some type of plants in their big water pools/ Terrarium. I plan to change the water every day so I don’t expect them to do anything except look pretty and maybe give my hermit crabs enrichment. I currently am going to have 2 liter pools, and they will also have air pumps in them as well. I was thinking about doing Duckweed, or some type of plant that will float in the water. What would be safe/good idea to put in the pools? As you can probably tell, I have never had fish so I’m not well-versed in aquatic plants.

What Moss could I use in my terrarium that won’t harm the hermit crab. Do you use any reputable dealers or brands to buy this moss from? I’ve heard some stories about fake/dyed moss.
My last question I have is, what plants could I put on the coconut fiber, or even leave out?
I really don’t mind my hermit crabs destroying anything. I can always replant if I need to! Thanks again for all the help I get on here.

I don't have any experience putting plants in the cage but I'm curious about this too.

I do have one interesting experience to share here. I have a spider plant (Chlorophytum comosum), that hangs onto the floor from my kitchen window. My crab Busy on her evening walks has many times paused there to eat portions of the leaves. For a long time I would just grab her when I saw that and put her on the couch. She often kept a piece as I did so and would continue munching on it. I was relieved to learn on Wikipedia, "Spider plants are non-toxic to humans and pets, and are considered edible". This plant is extremely low-maintenance and indeed, sends out baby plantlets ready to colonize new sites, so it would be very easy to put a plantlet in your cage every few weeks. If I was planning on putting it in her cage though, I would research it a little more, since Wikipedia sometimes has errors.

I did see some peat moss for sale in the Petco, and I would feel safe using that (it is sold for reptiles). I would suggest starting with that (on the substrate, not in the pools, since it is terrestrial), although I haven't tried it (yet).

Have you had a look at JJ's plant guide, and the care sheet about moss? There's tons of info there!
