Hi all. I believe I already know the answer to my question. I bought 2 azure damsels awhile back to cycle my quarantine tank with, after adding doctor Tim's one and only. I bought these fish knowing they are jerks, but also very hardy. My original intent was to give them to a friend or the lfs after my main display was set up and ready to accept new fish from my quarantine. The problem being is the main display tank is now ready to go and my wife has developed a close personal relationship with the damsels. I know it is not a good idea to introduce them as the first fish to the tank. But, I'm trying to keep a happy wife and therefore a happy life. Any suggestions as to whether putting them in the main display first is going to cause any real harm would be greatly appreciated and thank you for your input in advance. Also, the tank is 90 gallons.
