Condition/Dechlorinate ALL WATER before offering to hermits.
When washing or boiling ALL WATER MUST BE CONDITIONED.
Make sure Humidity and Temp are at the right levels.
Feed hermies a balanced diet of fresh foods.
Provide your hermies a home free of chemicals, pesticides & perfumes. (While house cleaning make sure you cover the top of your tank so no chemicals get in the tank).
Have more than one hermit crab. They get lonely!
Provide extra larger shells for your hermit crabs as they grow they need bigger shells.
Boil EVERYTHING before offering it to the hermies. Shells, dishes, all their toys and climbing stuff. For stuff that can't be boiled soak in warm salt water for 30 mins and rinse, let it dry.
Check for mites and other illnesses before introducing your new crabs to the tank. Isolate new crabs atleast for a week before putting them into the new tank.
Feed your crabs preservatives, such as copper sulfate or ethoxyquin (EQ).
Overcrowd your tank. Hermies need room to walk and play. Too many herimes in too small of a tank can cause territorial fighing. Leave some room for growth as well (unless your goal is to buy a bigger tank.) With the proper care, your hermies may live many years and can grow to the size of softballs!
Dig up a molting crab unless it's an emergency. Leave them alone they know what they are doing!
Keep your hermies in a plastic critter keeper! GLASS TANKS ARE THE MANDATORY HERMIE HOME!
Use vinegar to clean the crabitat. They have cleaning supplies at pet stores for reptile cages. One being "Wipe Out".
Put any metals in your crabitat. Metal will break down and rust. Rust is harmful to hermies.
Handle hermies excessively. They get scared just like we do. Going in and out of the tank stresses them out because of the humidity and temperature changes.
Offer your hermies painted shells. Painted shells often chip and peel. The paint is toxic to hermies. Even if it says NON TOXIC.
Don't feed your hermies food containing spices, table salt, or refined sugar.
Wash anything with soap or put in dishwasher.
Put your hermies near a window or in direct sunlight. They will suffercate.
Put your hermies near the vents.
