Vampire Crabs

[Noahsfish]

There's basically no where that imcould find enough info on vampire crabs on the web...I know their basic needs, but wasn't sure on how much water and how much land they need...I know they can't live in an all aquatic habitat, right? And how much water/land do they need? Does the water need to be filtered? How would i do that while still having lots of land? How small of a tank and how many do I need. I have a 10g but I'd rather use something smaller like my 2.5 which I'm still setting up. If the 10g is minimum tank size then it's basically a no for me as I already have plans for it...I'd like to just keep one if possible btw...

They are great!! From what I hear, they would rather have a deep bowl of water and lots of land, rocks, moss etc
