So I added a pink streaked wrasse to my established 40 gallon reef tank with a lawnmower blenny and a black cap basslet today. The wrasse swam around a bit then hid away in the rocks. A few hours later I noticed the wrasse swimming around looking somewhat stressed so I watched him for about 10 minutes and a couple times when the basslet would come out he would chase and nip at the wrasse. When I noticed this I turned the lights out and the wrasse swam away and wedged in a rock to sleep and rest. There is a a good amount of live rock and the basslet has always been the nervous type so I am hoping this is an adjustment period but wanted your guys thoughts on if they will adjust, thanks all.
