An Oscar may turn from black to grey if it is frightened scared or distressed in any way. Fish like Oscars tend to show much darker colors when their surroundings especially the substrate is also of a darker color and vice versa. If my oscar is hungry he ll go all green if he sees me with a big juicy rosy red or earthworm hes all black and when he chases other fish in the tank around he turns grey.

Moreover oscars will also often change from black to grey according to their tank environment.

Oscar fish Oscars always change color I dint really know about this permanent colour change thing but they definetely do change colour sometimes. Cichlids change color according to their moods and the environment. In some cases their colors can change drastically within seconds. I doubt that your oscar really should be dark black because i ve never seen a dark black oscar and i ve seen many many oscars . The oscar fish astronotus ocellatus is a type of cichlid and a member of the cichlidae family.although there is an enormous selection of oscars available today originally there were only three parental types of red albino and tiger oscar fish. All these variations are the products of cross-breeding. This species was first described in 1831. I have a 120g tank and in it i have 2 oscars 1 white and a black. The black oscar turned grey when he was first introduced to the tank but quickly adjusted.

Recently it has turned grey again one day its whole body will be grey others only half but doesn t act strange or hide. Its eating well and is getting along with the other fish. Just don t why its discoloured. The darker a humans skin the more melanin pigment it contains. The same is true for fish. A good example of a fish which has been selectively breed for enhanced melanin pigmentation would be black lace angelfish. An absence of melanin means that the affected animal in our case fish will have no black brown grey or green coloration. blue oscar fish for sale oscar fish food wild oscar fish lutino oscar fish albino oscar fish small oscar fish oscar fish tankmates blueberry Fish can turn black as a response to discus disease a seasonal flu-like illness that causes the fish s skin to come off in patches and turn dark.

Some of them passed away suddenly without any reason but this one had turned silver grey and it was mostly on her sides and belly while back remained pure black. I m just trying to find out of anyone ever had experience with black molly turning silver and dying within 4 days.
