Welcome to the board.......tell us more about your tank specs and more info on what you plan to develope........I've got a blue damsel thats been with me since day one.....currently it is in a 29gal that is just beginning to develope....was in my reef but I removed it and my domino from the reef because it no longer fit in those plans......seriously considering dedicating the 29 to be the damsel retirement center....in honor of there dedicated service to the completed cycle of my 2 55's.............
