No, a humidity gauge is not going to tell you how much water has settled into the substrate. The air in the tank can be relatively dry, while there can still be standing water at the very bottom which will drown molters and grow harmful bacteria. The droplets will always sink to the lowest point an...

My crab has been acting more alive for the past few days but I had to take out the third leg she's lost today. I don't understand why she's still losing legs

Does any purified water work as long as it's labeled "purified"?

If you’re also able to get out to a conventional store (or if your local health food store is a large one set out like a conventional store) with a butchery/meat/seafood counter, you can always try to ask someone there if they would be willing/able to give/sell you some offcuts to feed your crabs. ...

I do sympathize with finalxfantasy he was GIVEN these crabs without substantial care for them. He didn't ask for them. I feel sorry that now he has to deal with the repercussions and the guilt. He will undoubtedly take better care of them in his adult life, just like most of us did with hermit crab...

I searched on google and I can't get enough information about this water filter. Is this water good for the crabs? My parents say it filters out every chemical and purifies it 100%.

I can try that. I'm going to try to go to a health food store tomorrow to get things

I am not sure I understand - if your sister is slacking on her chores, can you not take up the slack and do her chores and earn her share of the money too? There are many other ways a 16 year old can earn money, too. Mowing lawns, shovelling driveways, baby sitting. You can walk or ride a bike to a...

I just wanted to chip in and agree with what Curlysister said about substrate depth. These crabs burrow up to 3 feet underground in the wild! I personally wouldn’t feel comfortable giving them anything less than a foot. If you really need to get the most coconut fiber you can get - check Home Depot...

It is imperative that living creatures eat and have appropriate food available to them, so scavenge through your kitchen with the safe list in hand and see what you can find for them. A quick internet search also yields the consensus that hallowe’en crabs need to have their water replaced and water...

I am going to be very straightforward and blunt. I am sorry if you are offended, but I think it needs to be said. You got an exotic pet that you are not able to care for, and it will most likely die because of that. A quick search online led me to the advice I will post below. I'm sorry, but my sis...

1. What kind of substrate is used in your tank and how deep is it? I have coconut fiber and its not very deep. I haven't been able to get more substrate for that tank yet. 2. Do you have gauges in the tank to measure temperature and humidity? If so, where are they located and what temperature and h...

I was reading that Halloween crabs might be foaming at the mouth due to dehydration... I have no experience whatsoever with these types of crabs but I did a little bit of research to see if I could help. So has he/she not had an water for awhile or not been drinking? shes been drinking and getting ...

her legs also arent working properly and she smells strange. my halloween crabs also cannot fully submerge their body in water. I think my dad failed to get the right setup for my tank in a few ways when he gave them to me. There isnt enough substrate and i havent been able to afford more. i feel li...

I know nothing about this type of crab, but presume the needs are similar as far as substrate, heat, humidity, and diet. It does not look like you have enough substrate for such a large crab. What are your tank conditions? What do you feed it? How large is the tank? Edited to add - Please fill in t...
