Blue Spot Jawfish with Actinics

[Djbetterly]

So all day long my jawfish is content, he doesn't seem stressed or anything. As soon as the evening comes and only the actinics are on he gets very stressed and appears anxious.

Has anyone else experienced this?

He has more than enough rubble around his home and he built an additional home that he goes to every now and then.

The temperature is between 77 and 79 degrees, pH is around 8.1, nitrates are less than 2 and salinity is 1.025.

I hate seeing a fish stressed but this is the only time of day he is this way.

most jawfishes does that. i don't know why, but I think it is the sudden change in lighting. if you can graduately dim the lights, it will solve the issue. still no harm is done. only a few of my jawfishes does that.
