Small wurms in my substrate. OK, or not OK?

  • We are currently upgrading MFK. thanks! -neo
There will be loads and loads of them. Thing is there will be loads and loads of little things if you've used live rock, the diversity is just huge. A lot of the things aren't that bad though.
 
There are a growing amount of things in the substrate. One bonus: I got a handful of baby snails in my last live rock purchase.
 
I was wondering, will an Arrow crab get along with other hermit crabs and shrimp? Asked in another post, but want to be sure before I buy one.
 
I have never encountered a problem with the arrow crab messing with any of the shrimp or hermit crabs in my tank. Although I had a friend who's emerald crabs would tear the legs off of his arrow crab. The one thing to remember is that not all arrow crabs eat bristle worms, it is a hit or miss type deal.
 
get like sand shifting stars or somehting to controle them..
 
I haven't seen a wurm in my tank for days, I don't think the problem is that bad.
