#1 What kind of crabs are these?
#2 Are they bad?

I got new shells for the hermits today. Hope they get into them....

More crabs and the hermits too...........

I was bored and caught them up close. There is at least five kinds of these crabs (red ones) in the tank.

those red hermits look like mexican red legs that I have seen before. But they could also be much larger species. I looked around for those hairy looking ones and all I could come p with is that they are probably predatory. The little red guy almost looks like a mithrax crab but the claws aren't quite right.

My wife is posting these (I am at work). Yes they are scarlet hermits. I bought 100 of them.

The first three crab pics I would agree are probably preditory. Although, not much of a threat while small, they may be later on. The red crab in the middle does look like a mythrax crab. An algae eater like the emerald.

The last hermit looks like a scarlet hermite, a great addition. The red looking one looks like a mythrax like fluff said.

The hairy looking crabs could be a type of decorator crab but I doubt it. In a tank your size, they shouldn't be too much of a problem, as long as they stay somewhat small you might be in the clear. You could try setting up some glass cup traps baited with some meaty foods.
