Fish aggression with actinic lights

Rfsmith4 · 05/08/2014, 05:36 PM

Has any one seen any fish aggression when the actinic lights come on. It's started in the last couple days with my damsel ( yes I know there a aggressive fish but he's been a model citizen for a year. And he was also my first.) My damsel will chase my sunburst anthia. Never nips just chases him back into the rock work. When all lights are on they get along fine swimming right next to each other.

Thanks for the help

Maybe be he wakes up to find the Anthia on his turf.

You may need more hiding spots. If you have a lot of flow in the tank and there are only a few spots that are gentle they may be fighting over sleep territory. During the day it doesn't matter but when they go into the rockwork at night maybe they are both wanting the same spot.

My angels sometimes chase each other a bit at night but nothing aggressive.
