Just wondering if anyone has any info... I have 11 green tetra in my tank and the other night I returned home after being away for a few days, a friend had been minding the tank so I wanted to check the fish were ok. I turned the light on and all the tetra bar one had lost their colour completely, the other one had gone from the normal blue to a bright violet/ purple marking up its side!
Anyone have any ideas what would be going on? Im presuming its because they were startled (rather than they were missing me).

cheers

I noticed with my neon tetras that they loose their color at night when the lights are out, it comes back once the lights have been on for a while.
Could be something similar.
