I have had my Majestic Angel for about 5 weeks, first 3 weeks he ate anything then he got whitespot, A tank with 16 fish but he was the only one and during treatment he started to hide all day and will not eat anything. The whitespot has cleared up with no visible signs but for 2 weeks he hides all day and will not eat. He does come out when lights go off but not grazing or looking for food. Is it just a matter of time. Any advice please.
