The Newbies Guide to Hermit Crabs
First and foremost use the SEARCH BOX and SEARCH, SEARCH, SEARCH! Our site has a ton of information and nearly every question that a new crabber is trying to answer, has been asked here before. We work hard to maintain a current and extensive library of articles to help you.
Have you found yourself an unprepared parent of a hermit crab or two? Are you prepared to give them the proper habitat in which they can survive long term? If so, here’s a very basic list of supplies to get you started.
A glass tank
- go as big as you can afford
- it doesn’t have to hold water
- it doesn’t have to be new (check the newspaper,craigslist, yard sales)
A secure lid for the tank
- a mesh lid with a solid barrier on top to retain humidity is ideal
- you can use saran wrap in a pinch but not ideal long term
- a piece of plexiglass or coroplast is a good cover for the mesh lid
- hermit crabs are escape artists! Place heavy weights or locks on your lid
Substrate for the tank
- 6-12 inches deep or 3 times as deep as your largest crab is tall
- Play sand meant for a sand box is perfect http://amzn.to/1PLQOMu
- Coco fiber which is shredded coconuts http://amzn.to/1KhJaHb
- Mix the play sand and coco fiber together, roughly 5 parts DRY sand to 1 part DRY coco
- We recommend Ultratherm heat pads http://amzn.to/2EVPmb2
- Can be insulated with Reflectix Reflective Roll Insulation or other DIY options http://amzn.to/1PLR1zg
- Place on the back wall of the tank to provide gradient heat. (Warm and cool zones)
- If you have a well lit room that will illuminate the tank during the day you can get by without a lamp. No direct sunlight on the tank.
- Be aware of how the room temperature rises during summer.
- They need a normal light/dark 12/12 hour cycle.
- We recommend Prime Aquarium Water Conditioner http://amzn.to/1PLRcu9
Ocean Salt Mix
- Not freshwater aquarium salt!
- Instant Ocean is the most common brand and is easy to find http://amzn.to/1SrKxnM
- These other brands are also good and may be available in your particular area: Fluval Sea Salt, Red Sea Salt, Coralife, Oceanic Sea Salt, Tetra Marine Sea Salt and Marinium.
- Cheap Tupperware works great!
- Water dishes should be deep enough for your largest crab to submerge.
- Provide exit ramps for small crabs
- Skip the cheap, analog gauge at the pet store, go wireless and digital. WalMart carries digital indoor/outdoor Thermometer Hygrometer You can also buy online. http://amzn.to/1KhJDZM
- Hygrometers should be calibrated prior to use
