HCA: Hermit Crab Association

Here are the sizes of my crabs: Teddy (1 1/4 in.) Mr. Eyeballs (1 1/2 in.) Marine (2 in.) Moss (1 1/3) If I have crabs that fall between the sizes on this sheet (https://uploads.tapatalk-cdn.com/20211011/eadf730815705988d04f2a973f6eaf24.jpg), would I round up or down for the crab's size? For example...

I keep the temperature at 74F. I think crabs usually like warmer temperatures, around 75-85 or higher (on the warmer end during the day, on the cooler end at night if possible, but tempurature fluctuations are not necessary). Otherwise, as far as I know about crabs (not as much as other people here...

Oh, yes! I've heard of wind chill before

Thank you!

Thank you! I'll consider it

Oh, okay! Thanks! I have two tanks that are different widths and I was trying to figure out how someone would put them together, but I guess that makes sense to have them simalar.

Thank you so much!

Okay, thank you! I just decided to put all four of my hermit crabs in the 15 gallon tank, and not get any more for now (till I can hopfully one day get a larger tank!). It was too much work, taking care of two tanks. I've been really busy latly, and thought I could keep up with two tanks, but it was...

Interesting! I've never heard of that, but it makes sense...
Thank you!

Sorry if this is a silly question, but what is a heat index?

I think you should probally just leave him alone. I've been researching a lot about hermit crabs lately, and if he is molting, he probally doesn't want to be disturbed. (Hopefully someone with more experience chimes in! About 85% sure you should just leave him alone :) ) You can switch him to the ot...

HCA doesn't subscribe to 'x gallons per crab' - it is really dependent on the size of the crabs. Here is our caresheet: https://www.hermitcrabassociation.com/phpBB/viewtopic.php?f=26&t=92541 Well, you said that a topper doesn't increase how many crabs you can have. When calculating space, we consid...

For your tanks, you're probably at or close to the limit already. A good rule is about 5 gallons per crab, so unless you upgrade to a bigger tank, I wouldn’t add more. Overcrowding can lead to stress and aggression. As for tote bins, a lot of people use them successfully, but the plastic can bow un...

Thank you!

Thank you! What is the best way to determine how much space each crab needs?

I saw this on another website recently: "A 5-gallon tank is enough for a Jumbo Hermit Crab A 4 -gallon tank is enough for a Large Crab A 3 -gallon tank is enough for a Medium Crab A 2 -gallon tank is enough for a Small Crab A 1 -gallon tank is enough for a Teeny/micro Crab" Seriously! I do not think...

So, I currently own four purple pinchers. They are a mix of smalls and mediums. I'm considering getting some more, but was not sure how many more could fit in my tanks. I have a 10 gallon tank and a 15 gallon tank. Does anyone have a suggestion for how many more crabs I could fit into my tanks witho...
