Do you need to clean a hermit crabs aquarium?

Yes, because the humidity needs to be a bit above average. Also, they sometimes prefer to drink out of a sponge. You need to have the sponge in a ocean-water dish that is deep enough for the hermit crab to submerse in. Thus giving a choice of drinking from the sponge, drinking from the water itself, or soaking in the dish - which helps with molting and gives the crab a natural option for bathing like he would have in the wild. make sure there are always BOTH fresh and salt water dishes in your crab tank - dechlorinated and de-metalled water is vital to your crab's survival! and the salt water should NOT be table salt! you need ocean salt - like oceanic or instant ocean found in pet stores for aquariums. table salt is harmful to hermit crabs.

He looks like crab bait to me." (Not attractive and/or clean) :>)

You can tell a land hermit crab from a water hermit crab by looking at the claws/arms or legs. If it is a water crab it will be blueish and if land crab it will be pinkish purpleish.

Also have a wet sponge for each kind of hermit crab in the crabs tank.

It all depends where you get the Hermit Crab from. I got two Hermit crabs when i got mine.

Because you never know you might find something at the store that you think your Hermit Crab just HAS to have. I know I did. TIP: I have also found that PetSmart is a little bit cheaper than PetCo, especially if you have one of their cards. And it's not that much cheaper than PetCo, BUT in the long run it will eventually pay off. I know that it helped me out.

Can 4 salamander live with 2 hermit crabs?

Not in a typical set up. Hermit crabs are scavengers, and even seldom documented hunters. They might attack your salamanders. Some salamanders also produce toxic chemicals which can harm a crab. Also, crabs need salt water, and salamanders have very sensitive skin. If your salamander wandered into the salt water by mistake, it would most likely die. It's not a good idea to house these animals together.
