my nem has been pretty shy this last month. he has been hiding behind my rocks out of site out of the light. at one point i thought he may have died. but today he came out moved all over the tank and found a spot right out in the open. he looks great but he won't eat. nomally i wouldn't care but i have not fed him in a month or so. does anyone know what to look for if he is sick? To me he looks just as he did when i got him from the LFS, except his foot used to be redish orange and now it is more yellow. water is good. ammonia 0ppm nitrite 0ppm nitrate 0ppm ph 8.3 calcium 480 the only variation this last month has been calcium levels. I test every week.
