Well if your an active fk, then you watch your fish, if you know and understand their behavior and gestures then you can tell after how they adjust to anything. My fish are rbp and they naturally live in dirty, muddy Bw, thus genetically they don't prefer bright lite, maintaining my Bw helps maintain their calmness and they are more comfortable. I think as fk we all owe if to our fish to Atleast replicate the conditions they are from as best we can, yes if their captive bred they don't know any better but their still animals. Any little thing that can be done to ensure similiar conditions is important imo. Keeping them in aquariums is hard enough on them. We could keep our water clear, but its not the color, its the quality of your water that counts.
