Hello. Thanks to everyone for making this a great repository of information. I've been lurking and learning for a couple of months, and after not being able to find an answer to my latest question, am posting my first thread. Most likely this has already been asked, and I just formed a poorly worded search.
We just finished cycling a 46 gallon FO
tank two weeks ago. About a week and a half ago, we put a Blue Devil Damsel in and it remained healthy. Two days ago, we introduced a Percula Clown, and the Damsel actually behaved quite nicely. The clown seemed a little lost so we put another clown in yesterday which is barely larger than the first. The damsel went nuts and chased the clowns, so I pulled it out and brought it back to the LFS
Today my wife called and said the second(newer) clown is continually chasing the first clown and appears to be nipping at it. Should we be concerned? From what I've read, they should get along in pairs. I don't know how to determine age, but they are about an inch and a half long. We just don't want to stress out the fish.
