Hi everyone

has anyone noticed a distinct pecking order with their crabs? There's definately one in my tank, and right now my biggest strawberry is top dog. I'm a nervous nelly, and I'm a little worried that there might be some issues with the pecking order. B (the big straw) eats like a horse! He can go through 1/4 cup of food by himself, and when he eats, he usually stays in the food bowl all night. Tonight I noticed some odd behaviour, when one of my smaller crabs approached the bowl, B pushed him away. It wasn't agressive and he didn't use his claws, I'm not worried at all about my big wuss hurting someone. I am however worried that my small crabs won't get a chance to eat!
Ok it's getting a little rambly, almost done

has anyone experienced this and why did you do about it? Should I do anything at all or am I just being over cautious? I don't want to up the portions, I just got them at about the right size, and I hate to waste food.
Thanks!
