im new to salt tanks and i have herd that damsles are very teritorial. wich is bad because i have a 8 gallon tank and planed to have 2 other fish. i thought maby if i added more live rock he couldent claim all of that rock his teritory. he dosent look that agressive and he hides when i come in the room. i was thinking he probably woulnt mess with a fish that is just as big, or bigger than him.
