Thrashing Oscar?

[2004exrider]

Anyone else have a fish that will just freak out from nowhere and start flying around the tank at night?! Once in a while my oscar will do that and ill see his lids start flying open and hear banging then he just stops and sits there. Anything i can do to prevent this???

Sometimes night feeders (cats,plecos etc) will startle a sleeping fish, what else and size do you have in the tank with the "o"?

you can try moon lights, then at least he will be able to see where he is going and what is around him. I agree with mr.pleco, it is most likely some other fish that is spooking him.

I thought mine was the only one that did that. Sometimes out of nowhere mine goes crazy too hitting all the tank walls then sits there stunned i think

Ahh! Good point, my pictus catfish is probably scaring the crap out of him. I have to always keep a bottle of melafix around because he's always scraping himself up. I have a night light by my aquarium but it might not be bright enough, i'll try and find some dim blue lights to instal for at night.

That happens to me when my delhezi is feeding at night and spooks the bala sharks. I've pretty much gotten used to big splashes and loud noises at night.

^haha, my aquarium acts like its possessed by the devil. The lids start flying open and closed and water is spraying all over the room lol. My walls and couch get soaked!

I've got a Tiger Oscar, about 8 months. He's always been a beast of a fish, but recently he began thrashing without provocation. As exrider said, i've got to keep a bottle of melafix just to treat his head wounds.

My assumption is that he's outgrown his tank although there's ample room from my perspective. I'm upgrading to my first non-tiny tank to accommodate him. I think most MFKrs would consider it a medium-small tank.

Hopefully this does the trick.

What is a recommended depth for oscars (/fish in.)? Is it recommended to keep the tank 10%> under filled to prevent the "demonic" effect?

yeah my guess is tank space mine started doing this in the 55 after i put a divider in to keep the 2 O's seperate (i know i know 2 o's in a 55 is horrible, even 1 is bad, but no worries it is very, very temperary, the will be moving to the 135 soon and the fish in the 135 to the 540 (or the 8 by 3 by 2 i build))

hmm i dont know. i had a 9 inch male Venustus that would ALWAYS patrol the front of the tank --back and forth real fast before the timer on the lights went out.. without fail he did it every nite. i figured he was exercising..

i moved him from a 90 gallon to a 180 and he did the same thing.. i never figured it out.
