Stresco: Take caution with that "strange looking crab" I had one piggy back with my rock, it had a slightly rusty orange color and was very shy. For a long time he created no problems. But then fish started to dissapear from my tank. It wasn't until 2 fish and an anenome later that I caught the crab with a clown fish grasped firmly in it's claws dragging it into the LR
Don't panic! it could be any NUMBER of crabs good or
bad. You should just make a good effort to identify that crab before leaving it in your tank for too long. JMO.
I love all the surprise critters on LR
. My latest surprise was a patch of what I thought to be some sort of green algae that turned out to be a patch of zoo's about 1 1/2 inches in diameter! they're tiny but they're growing!
