Sharing our crab tank idea

Hi, My son and I have having been keeping Hermies for quite some time now. This is the type of tank set up we have been using for quite a while through trial and error.
I thought it’s design may be of interest to others. We have taken a very ‘modular’ approach, which allows us to change areas of the crabitat quickly for decorating or cleaning etc. Most of our modules are acrylic rectangular boxes that fit very close together. there is currently a pot of growing mung beans but I have smaller acrylic boxes at various stage of plant growth ready for the tank, usually wheat grass. The right hand box is the filtered salt water pool with climbing rock wall and shell grit bottom, it currently has a nice cluster of live muscles that have been living in there for quite some time.The left rear box is mostly moss and the heat mat is under there, front left box is fresh water and the front is a shell grit sand mix the Hermies have been busily mixing around, the centre substrate is a moss/sand mix. We currently have 5 crabs in here, you can just see one in the background under the leaning Easter island head. Comments are welcome 🙂
