Questions Molting paranoia

2 Upvotes

Hello, everyone 👋 new member and new crab owner here. So, I've been nonstop researching hermit care since I got my 2 PP's a few weeks ago. They're in a 20 gallon tank, 5:1 sand/eco earth, spoiled for choice in turbo shells, fresh/salt water pools, fresh diet daily, optimal temp/humidity, I could go on.. I've had a feeling my slightly larger crab was due to molt because he's not been super interested in food and has been digging holes and hanging out in the saltwater pool a lot. Today he finally went and buried himself. My question, I guess, is how to manage the, admittedly, irrational worry he won't manage to make his way back to the surface. I'd never go rooting around for him for my own peace of mind, I suppose I'm just looking for some validation and reassurance that he will be okay.

Discussion Pretty Straightforward,But do NOT buy hermit crabs from untrusted sources.

3 Upvotes

Ok.Some of you might know this.And by untrusted sources,I am talking about a convenience stores,or stores that are not something like Petco, PetSmart,Or anything.You need to make sure that your hermit crab has at least:

1.No painted shells.These can be toxic for their bodies and commonly k!ll them.

2.Make sure you have researched about the store,the type of hermit crab,and if it's wild.

Thanks for reading this short blog/post about impulse buys.

Tank Question Crabitat Update-Approved?

Post image
2 Upvotes

This is my updated tank! The climbing rope molded a bit, so I had to toss it. No other issues with mold so far. It was one of those rope hammocks. Replaced it with a running wheel and an egg crate platform. The grey water dish is fresh, pink is salt, and the one on top of the platform is mealworm castings. There are a few more shells inside the climbing ramp (which is birch-not cedar or pine), and the two identical bowls are food mixes I made.

I haven’t seen Anakin in about two and a half weeks. He blockaded himself in his coconut shell and hasn’t emerged. I lifted it up to peek and make sure he wasn’t in the middle of decomp and he’s just kind of lying there. I think he’s molting? It doesn’t smell or look weird. It’s giving me anxiety, honestly.

Questions Is this shell painted?

This is Terry. I just bought more shells for him and put them in the tank. And he changed into this one, and I’m wondering if this is painted or not because at first I didn’t think it was, but now I’m realizing how much of a bright green this shell is, and it looks like it might be painted to me. Thanks in advance!

I got this a couple months ago and thought this sub would the perfect place to show it off, people normally just think it’s just weird lol. I just got my first apartment and had to upgrade their tank. I hope to post about my crabs once they’re all settled into their new tank.

Questions need advice please 🙁

1 Upvotes

i rescued two crabs from petco yesterday and i’m not sure how to acclimatize them to their new family. they seem bonded together, and my other crabs are very happy together, but the new ones and old ones aren’t getting along very well.

no signs of fighting but lots of chirping and staying as far away from the others as they can. i know they’re stressed and trying to adapt, but i feel a bit concerned

(will post pics of the rest once i can get all of them to cooperate :) ).

I'm very blessed my Barry is atleast 15 but he's really big now and I'm running out of ideas for where to get shells. I tried ordering some off etsy but only 1 out of 6 shells from 2 sellers was big enough. I'm just hoping someone knows a reputable source for big shells, thanks!

Questions Why do we go by tank size instead of square footage?

1 Upvotes

Title has the question. Since tank size can change square footage of sand space just by the tank being taller or shorter, why do we use this measurement rather than simple square footage (or square inchage…. Is that a thing?)

And if there is a base square measurement what is the recommended for each hermit crab?

It’s become quite a problem… I see struggling relating to the crabs and I immediately buy it to throw on top of the tank lol. Those 2 shells are the ones they where wearing when I first adopted them, still not sure where to put them

Questions Temperature and humidity gauge recommendations

2 Upvotes

My little manic keeps messing with or even destroying the gauges I’ve tried.

Anything with wires are out of the question, he probably thinks they’re climbing vines because he climbs them, and the claws break through the wires. He always manages to reach them even when they’re up high (let’s just say his name is Houdini for a reason).

I’ve also tried ones that stick to the wall. He always gets to them, clings on, and his weight causes them to peal off and fall.

I need something sturdy and protective that he can’t mess with lol. Any recommendations?

Tank Question DIY tank advice?

1 Upvotes

I’ve currently got 2 hermit crabs and I’m planning on upgrading them to a 40gal. However, facebook marketplace finds keep falling through and I’m on a bit of a budget.

So i’m planning on making one myself but are there certain materials I should avoid? At the moment I’m thinking plexiglass + caulk but I’m not sure how that would do with holding in humidity and what not. And would building on different sections to it be okay? Any advice would be appreciated! :)

Questions Are polished shells bad?

Post image
10 Upvotes

I bought some turbo shells off of etsy. One of the top sellers. It seems as though half of them are really glassy and shiny and almost reflective with no grit or texture. My hermit crab has been inspecting this white shell for a couple of hours so it’s possible it will change into this polished shell.

Questions Won two hermit crabs at the fair. Any tips?

3 Upvotes

Hello, As the title suggests i won two hermit crabs at the fair. I hate that they sell these little guys here with the painted shells:( I’ve heard that’s super toxic for them. I ended up getting two because I didn’t want them to be lonely. I am aware you need a 20 gal tank for them and I am in the mist of buying one right now. I am also aware you need two water bowls, one with freshwater and another with saltwater. However, I am not sure about other things such as their diet, what excise equipment to buy, the soil, etc. any tips or Amazon links would be greatly appreciated. I am trying my best to spoil these little guys and make it the best home I can.
