Re: Reacting to food

It could also be visual. At least if your new setup provides line of sight to the food in a way the old setup did not They should be able to detect food by use of "smell" over a distance of at least 5 meters. So it should make no difference that you rearranged your tank. (I don't assume you have a t...

Re: Mercury levels in Tuna

I think the two tank thing could work. Obviously, the more tanks and crabs you have. The more precise a result you would get. You could buy 3 crabs extra for each tank, and calculate with having to remove them. Expecting that a certain percentage would die before or during the time of their first mo...

Re: Mercury levels in Tuna

Good point with the crabs being closer related to insects, than humans. And in theory at least, be able to eat a lot of things, that could kill us. The fact that nobody has ever experienced a crab die, from something it ate, might be due to the fact that the crabs, like a lot of animals, avoid eatin...

Re: Spyder Robotics Herpstat 1 Review

That is very cool. Computers controlling environments with special needs is great.I know that manually controlling heat + humidity, probably is viable for people who live in areas where it's always hot and humid. Or people who put in a lot of work every day making sure the tank(s) stay at the right ...

Re: Mercury levels in Tuna

I might be overthinking the whole thing. Or at least I misunderstood the purpose of the lists. I had a good long look at the UNSAFE / UNPOPULAR foods list. Many of the plants on this list are deadly to humans and will probably kill crabs too. I guess the point with the safe and unsafe lists are that...

Re: Mercury levels in Tuna

I agree that pretty much everything is deadly in excess. At the same time I thought the point of the "SAFE FOODS LIST" is to provide a list of foods that can safely be fed to hermit crabs. You could argue that non organic fruit is safe. As long as you don't feed it in excess amounts, and maybe remov...

Mercury levels in Tuna

I noticed that Tuna is on the "SAFE FOODS" list. I am a bit puzzled by this because, Tuna contains mercury levels that are so high, they are considered harmful for young children and pregnant woman. I don't think occasionally feeding Tuna will kill or harm the crabs. Just like occasionally feeding a...

Re: Feeding hermit crabs, other crabs

Thank for the info.I am defiantly going to put crab on the menu for my hermits. Although I will probably not be able to source raw crab, and exo About the experiment. It would probably not be disturbing to most users. But I figured that the way he euthanized the "sacrificial" crabs was a bit graphic

Re: What plants are safe for my tank?

Why not just use plastic plants ? Having plants grow in the substrate may cause a variety of problems. Also the crabs might snack on the plants and kill them. They wont eat plastic plants. I guess if you really want to provide them with living plants you could look up information about the botany fr...

Feeding hermit crabs, other crabs

Sorry if this have been asked before. Searching for crabs as food for hermit crabs in this forum is pretty much impossible due to the massive amount of unrelated posts that contain the words "crab" the recommended food lists says that "Crustaceans (any and all crustacea including crayfish, lobster, ...

Re: Supermoon & Activity

I read an article about a small crustacean called Eurydice pulchra. The researchers exposed it to bright light around the clock. Eurydice pulchra have some kind of natural "sun lotion" to protect it from the sun. This "sun lotion" production was thrown off by the bright light. But it did not affect ...

Re: The moon and molting (straws)

It's experience with the tank that is recommended, as keeping it at stable temps and humidity, and keeping the sand at the right consistency, and a bunch of other little things (leaking water bowls, addition of too much moisture to up humidity levels leading to floods, etc) is a trial and error pro...

Re: The moon and molting (straws)

I am glad that I pitched the idea here so I got the understanding of why, it is a bad idea to set up a tank, like the one in the picture. I could add an extra tank on top and fill it with sand also. That way there would be a total of 35 inches of substrate. I have not read anything about bacteria gr...
