Fascinating and concerning. Here is the situation. Put 6 blue green chromis in QT a month ago. Went hypo to rule out some parasite intros. For the first 2 weeks, all was great. All fish adapted to hypo well, active and eating.
2 weeks in, I noted one fish hanging in the corner. No aggression noted, just hanging there and loss of appetite. After a week, this fish passed. I chalked up to a QT loss. Important to note, up until this death, the other 5 fish were active, eating well, and overall just looked great. Immediately after death, a new member of the 5 (not the smallest), immediately began a weak appetite and hanging in the same corner as the RIP fish. By the way, I know it is not the same fish that died as the sizing is larger. This fish remained this way for a week, and perished yesterday. Other 4 looking great during this time.
You know where this is heading. Yesterday, weak fish passed. Today, a member of the 4 is not eating and in the same corner! This is extremely interesting. I know this is a known phenomenon, but it almost appears that a new member becomes relegated to the culling immediately after previous passing. Like an understood pecking order. There is not aggression that I am witnessing. Food floats by the target fish and they could eat without hostility if they wanted. Just thought I would post this fascinating observation.
PS, starting to raise salinity now, so in a week these guys will be ready for display at which point I hope the cycle breaks.
