With the exception of one small Blue Chromis my fish are in the second week of hyposalinity. I had intended to leave the display fallow but I am unable to catch the Chromis. As soon as I come into the room he dives for the rocks. This Chromis has never shown signs of ich even though all the other fish had the white spots and were flashing. I know the meaning of fallow but there is nothing I can do. If this Chromis were to make it through the 72 day fallow period without showing ich, should I put the other fish back in the display.
