How much salt do you use in fresh water to make salt water for crabs?

Answer 1

You can make salt water for fiddler crabs. You need to use sea salt. Never use table salt. And you need to use distilled water or water that has been treated to remove the chlorine. You can get sea salt at a pet store. 1 tea salt to 1 gallon water. Change it often.

Answer 2

Whatever you do, DO NOT give your crabs regular over the counter salt, like the one you can get at your local supermarket, it can make your crabs very sick and die a slow and painful death. The reason why is because regular salt contains a lot of harmful things that can harm your crabs, so you have to buy hermit crab salt which doesn't contain does harmful chemicals.
