Figure 2

Change of EOD duration (A) and P/N amplitude ratio (B) in male RM4 (■) over 164 days, and males SM5 (○) and SM6 (▼) over 124 days (Treatment 1). Day-40: three then mutually stranger males (only RM4 shown) were placed separately in the three compartments of one common tank. Day 0: the two males that are not shown were replaced by SM5 (○) and SM6 (▼). Note EOD waveform changes in fish RM4, SM5 and SM6, in contrast to individuals M11(▽), M12 (□) and F3(*) that received No Treatment.
