HCA: Hermit Crab Association

At the end of December we received a large order of shells for our crabs. The first night one crab (Pinchy) tried a bunch of shells then picked one and the other crab Oscar jumped in the first shell he found. Oscar has stayed in the first shell he picked, but Pinchy changes shells frequently. Is it ...

Hi, we just purchased a 90 gallon tank (48" wide, 18" deep and 24" tall) we currently have 3 crabs, one is approximately medium sized, one is small and one is between small/medium. We plan on using a combo of playsand and eco earth 5:1. How deep would you recommend making the substrate....I have rea...

We bought a pre set up terrarium with 3 purple pinchers. The previous substrate was a little bit of dirt and a lot of moss. With the old substrate they were burrowed most of the time, we rarely saw them. Yesterday we changed the substrate to play sand/coco fibre with ratio of 5:1. We made sure the p...

We bought 3 crabs about 1 month ago. They came with their set up terrarium. We realized that the heat and humidity were way too low, so we have been working on that. We now have the heat up to about 80 and the humidity between 75-85. All three of them stay under most of the time and are eating a lot...

One of my crabs frequently burrows under the food and water dishes, so when I go to clean the dishes or add food, I frequently find him. I don't want to put the dish back on top of him because I worry he may have moved and would be squished. Recommendations of what to do, should I cover him in moss,...

A few shell questions: We purchased a pre set up terrarium with 3 PP. There were no extra shells, so we need to buy some. 1. If the crabs burrow most of the time and can't measure them do I just guess the size? Or how do I know? 2. Should I buy shells that are similar shapes to what they currently h...

Hi, we purchased some 3 hermit crabs and a terrarium from someone approximately a month ago. When we got them, the temperature and humidity were really low, we have been working on that, and finally have both good. Humidity around 85% and Temperature above 80 degrees. We are currently working on cha...

So I just purchased instant ocean Marine salt to replace the Aquarium salt we were using. Do we just mix as per the instructions on the bag? How much salt to water do you use? Our current salt water bath is too small. What size should the bath container be and how much water should be in it. Thanks

Thank you

I am buying a new UTH for the back of our terrarium. What size should I get? The terrarium is 24" W x 18 " D x 12" H I live in Canada, so am unable to order the ultratherm heaters as shipping is ridiculous. Available options: Exo Terra brand 11" x 17". Or 10" x 11" Zoomed brand 8" x 12" or 8" x 18" ...

Our substrate is dark sand and moss, not sure of types because it was in the terrarium when we bought it from the previous owners. The substrate is about 3 inches in most parts, 2 inches where low and 5 inches where there is a little hill.

So if we just use tap water with water conditioner that is preferred over RO water? Our current conditioner is "crabworks water conditioner" and says it "removes harmful chlorine, neutralizes heavy metals". Is that good, or should I get something different?

Hi, we recently purchased a pre set up crabitat with 3 hermit crabs, and I have some questions. 1. It was suggested that we purchase reverse osmosis water. We use the reverse osmosis waster as their fresh water and add Aquarium salt to it for their salt water. We recently purchased a mister (we have...
