Porcelain crabs in a 5g?

[monkeypie102]

So I'm wondering if having porcelain crabs in a 5g is okay? A seller on eBay has 5for $20 that I'm thinking of snagging... However my tank can't be upgraded for atleast another month (will be upgraded to a 26bf at that time) would that many crabs be okay for that long with enough food? I've got 7lbs of rocking but I've got 18lbs of dry rock laying around that I can break and drill if need be...

well, crabs are known to kill eachother. porcelains have to be spot fed but they love to hide which is a problem. you will have to replace about a quarter cup of water daily by drip. a 5g is hard to keep stable. a 10g is the smallest i would go.
