Ok I have a fresh water moray which I am slowly bring up to brackish , hes in a 20 gal long. Ive had him almost a month and I need to move him . I have a tank to move him into right now he is at 1.016 . My question is the tank I am moving him to is fresh water cycled so if I change it to 1.016 salinity will this kill all the good bacteria. Thank so much.
