That is why you only buy one Yellow Tail not 2. I thought the same thing when I was told this until I done it myself. The little guy hardly ever comes out. I usually only see him when it's feeding time. Now other Damsel can be mean. I know of some people that have used the shrimp and it will work, I am only telling you the way I have done it.
After he is in the tank for about 10 to 12 weeks start adding 1 fish every 2 weeks to allow the bacteria to establish for the load on the tank.
Might sound like a long time to wait and others will tell you about some snake oil you can add to speed up the cycle so you can add fish. It's your tank and your call on how you want to do this. I went slow because I want to have this tank for a while and not rush into problem and then sell everything I have because I'm tired of dealing with issues.
Hope the best for ya'll!
