Table 1. Chronic unpredictable stress schedule for Experiment 1 and Experiment 2.

Seven stressors were randomized; fish in the stressed group were exposed to the cycle of stressors twice over 7 days. Subjects were exposed to stressors twice a day at random times during the light period between the times of 9 a.m. and 4 p.m.

Experiment Day	Stressor	Time of day(Experiment 1)	Time of day(Experiment 2)
1	Tank changes (3 times)	11 a.m.	12 p.m.
	Cooling (23 °C, 30 min)	1 p.m.	1 p.m.
2	Lowered water (15 min)	3 p.m.	2 p.m.
	Net chase (8 min + 15 min rest + 8 min)	4 p.m.	3 p.m.
3	Crowding (250 ml beaker, 60 min)	10 a.m.	10 a.m.
	Heating (33 °C, 30 min)	2 p.m.	4 p.m.
4	Social isolation (250 ml individual beakers, 45 min)	11 a.m.	9 a.m.
	Tank changes (3 times)	12 p.m.	11 a.m.
5	Cooling (23 °C, 30 min)	3 p.m.	11 a.m.
	Lowered water (15 min)	4 p.m.	4 p.m.
6	Net chase (8 min + 15 min rest + 8 min)	1 p.m.	11 a.m.
	Crowding (250 ml beaker, 60 min)	2 p.m.	4 p.m.
7	Heating (33 °C, 30 min)	10 a.m.	10 a.m.
	Social isolation (250 ml individual beakers, 45 min)	12 p.m.	1 p.m.
