A tank with a topper to add extra climbing space

Hermit crabs are tree climbers by nature so maximizing all the vertical space in your tank will provide them with a more enriching and stimulating environment. Making use of all four walls of the tank will give your hermit crabs more room to roam and explore. Also if you use overhead lights you can provide your hermit crabs a way to get closer to the lights and warm themselves as needed.

You can get very creative in making second levels with a variety of materials. Just be sure the materials are safe before placing them in your tank. Avoid metal that can rust, paint that can peel and anything that might put off toxic fumes.  Evergreen woods are generally not safe.

Another concern will be growth of mold or mildew on the item after being exposed to the higher humidity needed in your crabitat.

Here are some suggestions for maximizing your vertical space.

  • Long climbing logs-use choya or other hermit crab safe woods
  • Hemp net hung with suction cups-avoid fish nets
  • Silk vines hung with suction cups- provides hiding places and climbing surfaces
  • Lizard hammocks or turtle docks with suction cups are great corner levels
  • Plastic baskets or shower caddy hung with suction cups
  • Cork bark wall
  • Coco fiber wall
  • Plexi glass with supports under it
  • If you are up for a project you can take a smaller tank and create a topper for your main crabitat!
