Here's an odd sounding one. Has anyone ever had the addition of lights kill fish?
My FOWLR has been up since Feb with no lights. Only have (had) 2 clowns, 1 royal gramma and 1 bangaii cardinal. 2 days ago added canopy with lights. Cardinal won't eat anything and one of the clowns was inactive all day yesterday and breathing fast & heavy and died overnight. No other noticeable signs of distress. All the fish have been in for at least 5 months.
Salinity 1.024
Nitrate read 0 on my API test kit (yes, I know the Devil created API kits and I'm a bad person who hates my fish)
Could lights being added after so long have stressed fish to point of dying?
