I'm not positive, but I'm pretty sure this is the first documented case of a hermit crab being able to reproduce in solid captivity. (As opposed to sitting outside half the year in an enclosure.) You have to share your secrets to happy crabs!
And about the babies going towards the light - that's a common occurrence in almost all water-dwelling critters when they hatch. Baby fish have been known to squash themselves up against the glass in aquariums so hard that they kill themselves. It's a normal response so that they are able to easily find the surface of the water, and therefore food. Unfortunately with aquariums and glasses the light comes from the side and confuses them. Wrapping the tank or container with a light-blocking coating like dark paper will usually stop it from happening.
Oh?

I didn't know that? I thought there had been others here at HCA that has had their hermit crabs reproduce in captivity.

As far as I know, I don't keep them any different from you guys, but I can write a list.
- About 70 gallon/263,25 litre aquarium (130x45x45cm)
- 80-85% air humidity. I spray the crabitat with a spray bottle a couple of times a day. I water my substrate now and then with a sprinkler bottle.
- Between 24-27°C at day, and 21-24°C at night. As heating (when it's needed), I use a ceramic heat lamp inside the crabitat.
- About 15-17cm deep substrate, sand and cocofiber mix (approximately 5:1 ratio)
- A lot of hideouts and decoration.

Cocohuts, mangrove roots, cork bark, coconut fiber net, fake plants, and so on.
- Two large water bowls with fresh- and saltwater. I change their water about two or three times a week, sometimes more often depending on how much they have dragged into the water.
- A pretty large food bowl. I feed them with fresh fruit and vegetables, cooked egg yolk, nuts as walnuts and coconuts, and different foods from THCP.

They always have access to THCP Surf-n-Turf Protein Combo Mix, and they eat from it several times a week.

I change the food almost every day. As calcium source I use THCP crushed oyster shell calcium supplement, which I spread out directly on the substrate.
- A lot of shells of course.
The hermit crabs living in this crabitat is two medium ruggies, one medium and two large indos, one large PP and one medium/large E. It must have been the ruggies, now that I think of it, because it is only one of them and the E that are females.

Yay, I know which hermit crabs who has been parents a short time today.
OH MY GOD! I just went to check them out, and WHAT DO I SEE?? The two ruggies, up in the coconut fiber net, and the female CLEANS HER SHELL OUT of unhatched or dead eggs/babies! The male hangs on her back.

My little sweethearts are close on giving me a heart attack, as many surprises as they have given me today.
The male hanging on her back:
The grey stuff between her claws is the eggs/dead hatchlings:
I got hold of some of the eggs.
Actually, there is something I am doing different from most of you all: I barely handle my hermit crabs at all. I just let them live their life without almost any stress or disturbance. Maybe that is the clue to this amazing happening? That is as close to nature as they can get in captivity; almost no handling at all.

I don't know, but I think that is important, since this is a wild and easily stressed out animal.
Now I'm going to bed. Here in Sweden the clock is 10:24 in the morning, and I haven't slept anything at all tonight. So good night to you all!
