Hermit crabs should NOT be kept in a cage. They need to be in a 10-30 gallon tank with enough sand to completely bury them - as they need to burrow when they molt. When molting they will bury themselves for as long as 1 week to 2 months. If your hermit crab has nowhere to bury themselves when molting they will either retreat into their shell for 1 week - 2 months, or may even die. PLEASE do the proper research before buying hermit crabs.

Pet stores may tell you that you can keep them in small cages with a sponge for water, but that is horribly incorrect. Hermit crabs CANNOT breath in regular air. The air needs to be at least 70-80% humidity, and they need to be in a tank that's at least 70 degrees fahrenheit. Hermit crabs can live up to 30 years. Most people only have their crabs from 1 week-3 months because they do not know how to properly care for them.

If you own a hermit crab and do not care for them as stated above PLEASE look into either acquiring the proper tools needed for their care, or consider turning them over to an animal sanctuary that cares for hermit crabs.

How do you prepare crab legs?

Usually crab legs are cooked when you buy them so you only need to warm them. I find the best way is to steam them. I put a veggie steamer in a large pot and only put the water to the level of the steamer. I put old bay all over the crab legs (some people use crab boil also) and when the water boils I put them in the steamer. I boil for about 10 mins or until hot. You can make a cream sauce to dip them in or melt butter. I heat heavy cream for about an hour and add a lot of butter and cook for about 10 more mins then I squeeze a lemon in the sauce. Its perfect! Easy and quick. Boil the legs with Old Bay seasoning added to the water. Cook until they turn orange. Dip in melted butter when ready to eat! There are healthier alternatives to dips for crab legs there as well and some really good crab meat recipes.
