How do you guys feed Vampire crabs?

[Sgooosh]

hi!
I've been experimenting on feeding vampire crabs, how do you guys feed them? I currently am thinking of putting a little feeding tray and putting food on there for them to find it
Will they fight over the food?
How often should I place food there?
How many food dishes should I have?

Currently, I have three, hoping to get a breeding colony going.

I used to put my finger in their enclosure and let them drink my blood =

No idea really about the vampire crabs but most crabs are greedy and will eat as often as the food is made available. If they don't get fed enough they tend to eat each other. With various marine crabs I kept, I would feed them 2-3 times a day and spread the food out so one crab didn't grab it all and hide with it.

You need to keep the water clean otherwise they die.
