powerhead reducing aggression

Mon Mar 12, 2018 10:24 am

I put a powerhead in my tank and I have found that distracts the fish and seems to reduce aggression. Maybe its because they are having a lot of fun or maybe because it takes more effort to swim. If I have the powerhead off they tend to spread out around the aquarium and chase each other around more. When I turn it on they huddle together with less aggression.
