Hi guys. I know what I need to do to a point. But I currently do NOT have a QT to use so can yall just give me a break down if possible? My Yellow Lab I assume is a female because she has no black stripe but still young. Anyway she is not eating. She's swimming with everyone else and they were all eating yesterday I didn't see them eat this morning because I have to feed and leave for work. So I get home and she's just hanging out at the bottom of the tank. When I went to feed them she got moving and started swimming with them but not gathering any food. She started following the other female (what I assume is a female) and that's it. But no consumption. She also has a small black dot at the base of the tale before the fin, I did not see that there on any of them before. She doesnt look lethargic or anything. All fins are opening and closing like normal but I know fish are always hungry. Please tell me I'm being over concerned and that it's nothing but stage fright. Also...there is one tank mate trying to dominate the whole tank. He even picks on the big chailosi. Idk if this may be the issue. This lab is probably the smallest of the bunch.
