15 gallons would be good for five hermit crabs at tops.
25 tiny 20 small 15 medium 10 large 5 jumbo I'm not absolutely positive that this is correct but you can always ask an expert! Hope this helped!
It doesn't matter as long and you have food, water, and some sort of shelter. I have seen hundreds of them together.

I'd say no more than 6 medium sized crabs in a 55 gallon tank.
Up to 2 small ones or 1 big one.
When you have a 20 gallon tank for only 2 or you have 30 hermit crabs, bubbling thing in water and dont have any friends execpt hermies
It depends upon the size of the hermit crab. You can fit 5-7 small crabs in a 10 gallon tank but only 1 or 2 large crabs. The more room you leave for your crabs the happier and healthier they will be. be careful not to overcrowd your tank, cos the hermits can get stressed, and may leave their shell or crawl into a corner and sulk :) But probably two or three would be enough room
then get them! in fact, PLEASE do!! they love company and will become depressed if they don't have any. make sure to have a 10-gallon tank for two crabs though~
Hermit crabs and turtles NEVER should go in the same tank! hermit crabs need a ton of humidity, and turtles don't even live near hermit crabs, plus hermies can drown. Hermit crabs need their own tank. 2-3 small hermies need a ten gallon tank. I don't know about turtles, i would also get ANOTHER ten gallon tank.
Yes its very good for the hermit crabs body!
i suppose they could fit, but they need lots of room to move around in. So a ten gallon tank would be the smallest size for two hermit crabs to live in
No hermit crabs need high humidity (70-85%)
You already know what temp, humidity, kinds of water, ( if you don't google how to take care of hermit crabs) You can have alot of space like 3 small hermies in a 10 gallon tank and have diffrent shells, climbing toys (not too many) diffrent foods (hermit crabs are scavengers they can eat people fruit and veggies).

Well for the safety of your hermit crabs i would use the basic rule of 1gallon of tank space per hermit crab..... so you could get any size you want.... but lets say you had a 10gallon tank so you could have 10 hermit crabs in the same tank.
