Will Sally Lightfoot Crabs fight each other?

[SINNERMF]

Will Sallys fight each other or other crabs? I've heard of them attacking fish, will they attack anything else?(shrimp, stars,...)

 

[ndfish]

Yes, sally's will fight each other if you have to many. They will not attack fish or anything else. I have Sally's in my 300 gallon reef along with other inverts ( safe)

I would not consider these safe all the time.
-Mine have killed and eaten my small sexy shrimp and my chromis and any weak invert/fish. They will kill and eat some small fish and inverts if given the chance.
