HCA: Hermit Crab Association

It is hard to understand exactly your substrate from first post. I see colored hermit crab sand, then put down coconut fiber. If you replaced the colored sand with just coconut fiber then it's fine for crabs but probably want to mix with clean sand soon. If you mixed that colored sand with the fiber...

Yep thin stripe. I live in Niceville and this the only native species I have scene here

Since 0 is really close to 9 that makes me wonder if the temp is 96. If so then would be a reason for streaking.

From the price I would say it's a college textbook. If that is required for the course they can bump the price pretty high. However once students pass they sell it used.

Mine have fallen in my tall tank on edges of water dish, hard objects, etc. They are always fine. I mean I wouldnt drop them on purpose but falls happen and not much you can do when it does.

Edit: I would probably make substrate deep since you don't have much of a footprint.

The sub is a little over 8" deep and the set up only has 3 crabs

Only about 60gal but the door makes everything much easier to manage. Also being wood I could mount my ceramic heater and a dimmer switch on the side to control temp. The UV light and night viewing light were super easy to mount too

No false bottom, mine has never leaked but I did a test prior to using it by filling and setting on paper towels for a few days. Every time I clean it I inspect it. I did just do a sub cycle, where I mix the sub from bottom and top together and there was no standing water. Taking it out is easy for ...

I use a small painters tray. You can get them at Walmart or a hardware store. To prevent drowning I have a plastic mesh zip tied at the lip with silicon in the bottom. This is my fresh currently. In prep for a Strawberry I want to get my sea water is the old critter keeper that my first crabs were s...

Did he recently change shells?

If so he is likely modifying his shell. They produce a chemical that dissolves the shell slowly while rubbing with their little legs inside. Sea shells are thick and strong but land crabs need less weight and sea crabs need more protection.

This is usually a crab modifying their shell. They produce a chemical that helps them thin out the shell to fit better, make lighter, etc. if you notice some shells are "hot items" with your crabs that likely means they are already modified shells. Given the choice a crab generally chooses a "turn k...

I use a humidifier, a cool must one, and tubing into the tank. If you go that route get one with changable mist volume,dimmer switch, and a toggle switch for power. This allows you to use an outlet timer and set automatic mist times. Of course I have a DIY 80g tank and a ceramic heat lamp on a dimme...

He may be molting. I'm not sure because he is burrowed behind the coco fiber climbing wall. Never had anything but digging molders so can't be sure but no smell and hasn't been out for about a week. I just didn't notice but if molting he started around when I made this thread lol

I made a fountain and I took it out. I ran into a problem where the water leaked the wrong way and flooded the bottom. Luckily my molting crabs had just gone down so they came back up and went down again. So be careful, tubing comes loose rocks shift whatever the reason. Also the submergable pumps u...
