What is the difference between Blue-Legs and Scarlet Hermit crabs

[kyarnkid]

I have 10 blue legs and I have 5 scarlet reef hermits. I was wondering what the difference was in them. I noticed that the scarlet reefs are bigger and I noticed that they are not as afraid when someone looks at them. My blue legs always run for cover when I look at them. I have a 55 and I also have ten snails
I was wondering what benifits, if any, do the scarlets have over the blue legs? Do they just have a brighter color?
Thanks

typically blue legs are more agressive.

kYanrkid,
Again you are asking all the questions I asked when I first started. The blue legs are more aggressive, more active and are much better at celaning up the tank. I have both and the scarlets never leave the LR to clean up the substrate.

So the scarlet are basically just for colors. Well I think they are neat, but I will stay with the blue legs for more quantity.
