HCA: Hermit Crab Association

Yep. This is still fine to use. This mix is slightly different composition compared to the regular salt mix that red sea makes, the trace element ratio is slightly different in accordance to what SPS coral needs. But it will not impact any detrimental effect to the crabs.

Eh, I would say it's safe. I know fan palms are common botanicals in aquariums, and I've seen shrimp keepers use palms in their tanks. For me, that's as safe as anything - many freshwater shrimp species and furthermore, breeds are incredibly sensitive.

The new set-up looks amazing, honestly looks like an amazing tank for them to get settled in and destress!

Hopefully in the coming weeks the crabs take full advantage of the space!!

This is so cool! I have a question for you! Do you think that if we could replicate the sound waves crabs hear in nature in captivity that it would add extra stimulation and be beneficial to them? Do you have any ideas on how we could do this? There is so much to cover, and I think that it's a grea...

During the Morphology presentation at CrabCon, it came up that hermit crabs likely can't hear sound through the air as we/birds/dogs/etc do and most likely feel vibrations instead. Thus youd have to turn on the sound machine quite loud to have it reverberate through the glass and the substrate, and...

The light output on these would be so minimal I doubt it would cause an issue. I'd just ensure any glow in the dark objects are out of the tank, as the materials used as the majority have not been tested with animals - in particular, crustaceans.

If he has hardened from a moult, no it won't continue to 'calcify' and get more rigid. They moult frequently to keep 'in proportion' to their internal mass of organs. A wheelchair honestly wouldnt help a whole lot, and just seems like an unnecessary stress to put the crab through to placate your fee...

Exotics require a little more work than the 'standard' PP, so I would suggest holding off Exotics until a little more experience gets under your belt. If you're head strong on Exotics, you may have issues in obtaining them, as crabs in the pet trade are becoming a little more uncommon, and hermit cr...

White tree frogs get too big for a 10g. Other frog species, like dwarf African frogs would do a lot better. If headstrong on frogs, poison dart frogs could work (some of the smaller species, like Thumbnail dart frogs. Some of the smaller species of toads could also work as well. I honestly like nano...

To answer some of your questions: - pools deep enough to submerge providing they have an easy way out. You can use fake plants, rocks, needlepoint canvas... as long as they have a easy/good way out (or good ways!) they will be fine. Heck crabs will even use airline hosing, so you don't have to be th...

Just add in gently (use a cup or something similar to avoid dumping in the sand, as when you dump it in it can be a little too aggressive and cause tunnel collapse). Once added, don't pack it down. Also do not remove large decor (rocks, wood, bowls) as crabs commonly dig underneath and can lead to t...

Great photos!

Wouldn't recommend buying if you can avoid it. Partially to reduce pressures of wild capture of crabs, but also cause online stores that sell exotics (blues, straws ect) come with a bad rep and likely to give you the wrong species at the best case scenario, dead crabs or run away with your money at ...

Looking really good! Congrats on the new guys!!

It be interesting to know the chromosomal make-up of our hermits, and sex linked chromosomes/genes. It would play a better descriptor to determine male vs female, and if our crabs are indeed intersex, expression of these genes would paint a far clearer picture. Intersex while common in many animal s...
