i have noted an odd behavior with my boesmani rainbows
at night they turn the rich deep purple and orange they should be when the lights are off, but after the lights have been on for a while they turn back to pale blue and yellow. also during the day they hide in the plants more.
does this mean they need more plants to feel safe?

It's possible that the intensity of the light is stressing them. More plants/driftwood might help to reduce that stress.
