    Default Help oscar attacking itself!


    0 Not allowed!
    So I set up my Oscar in a 75G tank. I previously adopted him a few months and he was living in like a 35bowfront. Anyway, I'm happy hes in his new tank, but when I turned the lights on today his color looked terrible, I can tell he was stressed. (More stressed then when he enter the tank yesterday, he gained his color back very quickly yesterday and the move wasn't to stressful IMO.)

    So anyway, its seems like he (not sure if male or female) sees himself in the reflection of the glass and is trying to attack that animal (which is just a glass wall).

    Heres a picture of him, as I snapped it he started attacking again. I turned the lights back off, not sure if its helping)

    You can see above the orange that there is loss of color.

    Interesting, if you look into the tank through the side glass do you see your reflection? Probably not if your only looking through one pane of glass. What's out side of that pane that he may be seeing? Remember a fish that size can see fairly far.
    Can you dim the light on the tank? Maybe the Oscar is not used to the amount of light you have and just needs some time to adjust.

    If all else fails maybe tape some background to the sides of the tank he's being aggressive too.

    I take it your tank has been cycled and is stable.

    Please remember; every keystroke has a consequence.

    Yeah the water is fine. I already had cycled filters to run and even tested the water right before. We taped construction paper in the sides. I have two 24" lights (compared to one 48") maybe I'll put one on so its less light.

    Also he moved from LED light to florescent.

    When I looked through one side panel I could see his reflection.

    I'm still a newbie, but I say plants. live plants are easy and inexpensive to install. They provide security for your fish if he wants to hide (haa haa, mine think they're hiding but they're not) they allow a dark shady spot if your fish wants out of the bright light, and they also improve water quality as long as you take out any shed leaves or debris. I put my plants in three weeks ago. I love them, they are also aesthetically pleasing.

    this sounds silly, but try turning his florescent light off and shining the LED on him. This could be why his color looks so bad. Some of my fish look great in incandescent lighting (which I only use to warm the water when needed) others look better when I take the hood off and let the light from the window in the tank. My pale red halfmoon female betta looks like crap in the sunlight to be honest, but she's beautiful in the false lighting ;(


    p.s. that may also tell you if it's the lighting he's upset about.

    No plants for oscars! Unless you want to witness plants being torn to pieces.
    Your oscar is just bored, the only way to entertain himself is attack glass or whatever he sees through it. Mine did same thing when it was by itself in a 55g. Now he's with neighbours and has buddies to swim and play with in a 210g.
    Get him some company, another Oscar similar size would be ideal. They'd sometimes fight and that's ok, it's in their nature.

    Oscars do not have human emotions like loneliness. They are not a schooling fish. Being a cichlid, they like their own territory, and like to be dominant, which is why they attack the glass relfection. The reflection shows no sign of backing down, and therefore they keep attacking it.

    I agree. Eliminate the reflection and the problem will go away.

    I do not believe that fish can see their reflection in the glass. Stick your head in the tank and you will not see your own reflection - you will only see out of the tank. You only see a reflection when looking from the front through to the side (two panes of glass, as others have pointed out already). This is a very common misconception with tanks. The Oscar must be seeing something outside the tank that's frustrating it.

    I'd cover the glass he/she is attacking and give the Oscar something else to do - is there anything in the tank to enrich the environment? Rockwork and/or driftwood? You could put a ball or two in there for the fish to knock around the tank and keep him/her occupied. They are quite large fish and therefore need a bit more stimulation than their smaller cousins.
