Okay so i have 2 fiddler crabs, i know im supposed to add salt so i did but aquarium salt is that okay? or has it to be marine salt?

Most experts recommend putting aquarium salt from the pet store in the water. If you place them in normal saltwater like the ocean, they'd die faster than giving them plain water. What they need is brackish water, with about 1/5 as much salt as normal salt water. For more information, visit
