Hello! I am new to the HCA and to owning hermit crabs. I currently have 3, two have been with me for about two months now, the third about two weeks. All three are different sizes with the biggest being a bit smaller than a golf ball. They are in a 10 gallon tank, looking for a 15-20 gallon for more room. I give them fresh food daily and water either daily or every other day depending on how dirty it is. Tank is always around 82 degrees during the day and 78 at night. The humidity is always above 80%, 75% at the lowest when left without checking for to long. My anxiety keeps me always worrying about them and if im doing everything right. My main worries are low activity and dry substrate. The substrate is about 5-6 inches, bottom half is sand with EE on top with it mixed in the middle (if that makes sense XD), im fairly certain they can burrow as iv seen them dig holes up against the glass without it caving in, and they almost always half bury themselves every day hiding from the daylight. I mist daily... The low activity is probably me just being overly worried, or they are getting bored with their surroundings.
Crab names smallest to biggest: Morty, Traffy, Broly.
