Ok so I added a yellow tail damsel to my tank yesterday and I have read stories about them being small terrorisers but my RG has been messing with him like crazy and will not stop. I turned lights off all day yesterday after I got the damsel. He is eating he ate this morning and no fun damage after looking over him. His fins aren't clamped either. Should I give it a few days? Is the RG just letting the damsel know this is his tank? And also the damsel isn't just in a corner hiding it is swimming around but every few minutes I look over and the RG is chasing him across the tank then stops. Thanks guys
