Java moss

[Plasmoc]

Hello, I’ve been researching Java moss and it looks like it’s ok for hermit crabs, but I haven’t seen anyone talk about a grid like the attached photo. I found this at Walmart, would it be ok to use in my crabs tank? I’m not sure if about the metal mesh backing... or if it would even survive? It’s made to be submerged in a fish tank.

Tank humidity is consistently around 79-83%, but would the moss survive? Is the metal Backing a problem?

I wouldn’t recommend it because of the metal backing. It can be harmful for crabs to eat anything that’s in direct contact with metal. Also, you need to make sure the moss is organic so there aren’t any chemicals that can harm them. I buy my moss off of Etsy and my crabs love it. They all spend more time over the moss dish than anywhere else. Give me a few and I’ll post a link to where I buy from.

Both of these sellers are great. They both sell cushion moss and mood moss/frog moss which are safe for hermit crabs, and mine love them both. The first seller also sells Plume Moss, which is hermit crab safe as well.

I highly recommend the addition of moss. I keep my humidity between 78-82% and it stays alive (until the crabs eat it all ). I recommend misting the moss once or twice a week.

Thanks so much! I wondered about the organic factor as well. Thank you for your input I’ll check out those Etsy sellers instead.

Java moss requires moist/aquatic conditions in order to thrive. So best placed in the freshwater pool. The metal backing is stainless steel mesh, and will not corrode in the crabs environment and is safe to add.

If you want moss outside the bowl, you'll need to source moss that grow terrestrially.
