HCA: Hermit Crab Association

Oh nice, the new setup looks amazing. I love the amount of work that went into this, it shows. Looks amazing!

Best sources is what is on the carefulness tbh.

For photos, you have to use a third party app. Some like to download Tapatalk on their phone, others like to use websites like imagr, photo bucket *have to pay*, flickr or the like. As for dropped limbs or exoskeleton, if the limbs are hollow with not meat inside, then the crab preformed a moult. If...

Exposed eggcrate is fine! If you have any eggcrate left over, highly recommend making some levels out of it and making the background a little junglegym to climb all over, pop shells in ect. Can even line it with the coconut fibre matting to help blend it all in! (Also recommend some plastic vines z...

Im team change every couple of years, I usually change out a small portion every year. Waste builds up, and without some removal of it, it could eventually cause quite a build-up nitrogenous based compounds, which may effect the chemistry of the substrate - like increased acidicity due to build-up o...

1. What kind of substrate is used in your tank and how deep is it? [/color] Cocofiber How deep is it? Ideally you want the substrate to be deep enough to moult, 3x the height of your tallest crab. Usually for smaller crabs, works out to around 6 inches. 2. Do you have gauges in the tank to measure ...

No, not at all.

The little white ones look like springtails, however the larger ones look like booklice. However, it's a little hard to make out as the video quality is kind of hazy.

How long exactly have they been down? It's not entirely uncommon for crabs to spend months down (and only resurface at night, then go back down again) to chill, moult and then chill some more before coming back up. New crabs in particular are known to 'destress' by staying for a good month undergrou...

I’ll keep that mind in too, I was always told that they need buddies because they are very social This is one of those grey areas which is likely blown our of proportion. Many crabbers still adamantly believe this, however some of the longest lived crabs tend to be singletons and no change in behav...

Food ~ they don't eat a whole lot, and its best to remove regularly especially if not dried to reduce mould growing within the tank. Most people change out the food daily, or every second day. Even if they don't seem to touch the food, continue to offer a good variety to ensure all nutritional requi...

If you don't find another crab straight away, I wouldn't worry too much. Like Curly mentioned, crabs aren't exactly social, they just conglomerate in the wild to evade predation (safety in numbers) and resources scarcities.

Do you have values for each of the airlines (to the box filter and airstones?). Air will travel the path of least resistance, so its naturally going to flow to one or the other. An oversized pump will mask this, or valves so you can send the air to each location appropriately.

I've noticed them on mine too. It looks like a tuft of setae (hairs). I just spent a while searching and came up with nothing. I would guess it has a sensory function, but I suppose it could be some kind of grooming structure, e.g. perhaps for cleaning other appendages (e.g. antennae)? Just guesses...

I've added an unidentified Porcellio sp. in the past, and noted very little changes besides isopod species ratio in the tank. They still hid just as frequent as the Armadillidium sp. i had within the tank. So I think its entirely up to personal decision. True, faster species are likely to evade the ...
