I have a pait of tank bread ocilaris clowns in my 120g dt. They were purchased at the same time about 7 months ago as about 3/4 inches long. One is obviously the female and is twice the size of the other approaching 2 1/2 inches now. She has always been fat and healthy, and the first to come forward for food. Today she seems a little slower and did not eat with the same vigor. If anything, she looked a little chubbier today (but she is a pig and has always been a plumpish fish), but otherwise 100% healthy looking. Does this mean anything? Could she be about to spawn?
