Sometimes fish change colour because of the mood they are in. Maybe the fish is feeling a little bit stressed through changes colour. To be honest, I don't think is anything to worry about because I've seen this before myself.

I may not always be right, but I am always the BOSS :-)

Oscars are light sensitive, and really dont need any light. Natural light during day and room light in evening is good enough. If you must have a tank light, 2-3 hours in evening is plenty. Too bright or on too long will impair his vision.


I may not be the Boss, but I'm ALWAYS right!

sometimes fish also reacts with the color of the environment,
and can be stressed out by moving people.... however, once the fish feel
that any moving people means foods, they will react differently ...
