So a friend of mine has an oscar. I went to the store to buy it with him. At the time of purchase, the oscar was pretty dark with nice red streaks (tiger oscar). After moving into his tank, the oscar has faded a lot. He looks almost like an albino with just a hint of black in his fins. The substrate is sand and I initially thought this was from stress. However, whenever a hand is put into the tank, the oscar turns dark for a few seconds before fading back to its pale mode. Any possible reasons why? I can try to get pics tomorrow.
with everyone my oscar only sulked for 2 days it was only 2 days since he was by himself he is great now and eating well they are great pets once they get used to there new tank.
