Welcome to Hermit Crab Pool Boy Training 101!  We hope the following information will cover hermit crab water pools from a-z. If we didn’t cover something here please feel free to comment or contact us. Let’s dive right in, the water is fine! Your tank should have two types of water bowls or pools: ocean water made from marine-grade salt and freshwater. Tap water contains beneficial minerals and metals so we discourage the use of distilled or otherwise purified water. Tap water must be treated with a product like Seachem Prime to make it safe for use. Prime also binds ammonia. In our testing, ammoniaRead More →

Please note: As we do not have the necessary information to determine how land hermit crabs are affected by ammonia build up in the water and to what degree we err on the side of caution and treat our water as we would for fish. All information regarding Prime is based on the assumption it is being used in a stable fish tank. Our use is much different. Our primary reason for using Prime is to remove Chlorine and Chloramines and heavy metals from the water and Prime does that well with no recurrence that requires retreatment. Ammonia build up is only an issue whenRead More →

You finally scored that awesome tank at a killer price but now how do you clean it?? If the tank is simply dirty but no actual build up on the glass, the cleaning process is pretty straight forward. A mild detergent can be used with hot water to wash away dirt and grime. Use a mild bleach solution 1:10 ratio to sanitize the tank in case of parasites or disease. Follow up with a thorough rinse with water and then white vinegar. Allow to air dry 24 hours. Dealing with stubborn build up on the glass is more challenging. Some stains may never come off.Read More →

A couple years ago when we created our Facebook group to go along with our website I was shocked to find so many people with flooding issues and bacterial blooms in their crabitats. The response to this was a false bottoms.  In 14 years of crab keeping I’ve never encountered this, so it’s on my mind all the time…where is all the water coming from? I think I may be on the path to the root cause – overly wet substrate at the beginning. When you take sandcastle wet sand, add wet ecoearth, add bubbler pools and heat and it’s no wonder the humidity inRead More →

In hermit crabs, the fourth and particularly the fifth pereopods are reduced, usually remaining within the confines of the gastropod shell and hence are not used for walking. These appendages do however becoming important when the hermit crab attempts to right itself, providing anchorage within the shell. Further, the fifth pereopod has become specialised as a gill cleaning appendage, often resting within the gill chamber (Bauer 1981). On the abdomen only the left pleopods are retained (Poore 2004).[1] Hermit crabs used specialized setae on the third maixillipedes and fifth pereiopods for most grooming but used the unmodified first, second, and third pereiopods as well. MostRead More →

The land hermit crab (Coenobita) develops a water sac inside of their shell prior to a molt. As shedding of the old exoskeleton begins, this store of water is used to expand the body to stretch and increase size before the soft exoskeleton begins to harden again We are building image galleries of specific body parts.

All water that comes in contact with your hermit crab must be dechlorinated. Most cities add chlorine to their water supply. Some add chlorine and chloramines to the water. Unless you have contacted your water department and determined if they use both, you should use a treatment to remove both. In the past, it was enough to let water sit out for 24 hours so the chlorine could evaporate out. That no longer is sufficient because chloramines will never evaporate out nor ammonia. A bottle of water treatment will last for years. Distilled water is not recommended as it is devoid of beneficial minerals. StresscoatRead More →

written by Jennifer Nielsen The existence of an ocean water dish is a source of great controversy in the world of hermit crab owners. Why the importance of this type of water is rarely debated, it seems that the products used in the creation of Ocean Water are the source of much debate. Just as all hermit crab owners know not to use table salt for their crabs, there are two types of salt available for aquarium use. Fresh Saltwater as well as Ocean Water Salt, which although made of the same components have vastly different role within the world of fish keeping. A saltwaterRead More →

Hermit crab enthusiast Jennifer Nielsen compares several brands of sea salt mix in this article.Written by Jennifer Nielsen (aka redjln) While many hermit crab owners realize the importance of providing Ocean Water to their pets, there is a question over which type and which specific product is the best. To answer this, I got Instant Ocean and Reef Crystals enriched blend by Aquarium Systems, Doc Wellfish’s Aquarium Salt, and Aquarium Salt by Jungle. I have gotten a container of Distilled Water to test the products in. Now, I will disclaim right now that I do not have access to a laboratory of equipment. All IRead More →

No. Hermit crabs should not consume or be exposed to stress coat. There is no conclusive evidence that stress coat is beneficial to land hermit crabs. There is concern regarding stress coat coating the gills and abdominal lung. Water treatment products should not include any additive that promotes a healthy slime coat or contains aloe vera.  Read More →

Originally posted at All Things Crabby Things Hermit Crab Care Blog The first step to creating and maintaining humidity in your tank, is a good lid. A screen lid alone is not sufficient. A glass/plexiglass/lexan lid, cut to fit is the best option. Plexiglass/lexan can be purchased at most hardware stores and be cut to size for free. This can be placed on top of your existing screen lid for stability. Coroplast is another good option for a lid. This can be placed on top of your existing screen lid for stability. In the short term, you can use plastic wrap over the screen lid. SomeRead More →
