My Oscar fish is swimming in his tank like hes going crazy is he sick?

Question

He swims from the bottom to the top real fast then almost swims upside down

Answer 1

He might be hinting that the water needs changing. Do you test the tank for ammonia, nitrites, or nitrates?

When the water quality starts to deteriorate (which it can do pretty quickly with an oscar, depending on the size of the tank), they seem to try to "escape" at first, but then become lethargic, sit at the bottom or gulp at the surface for air, and can get red streaks through the body and fins.

If in doubt, a 25% water change shouldn't hurt.

Answer 2

I'd need a lot more information before I could help you, but PLEASE don't add other fish. Oscars are loners, and any other fish you put in will wind up being killed at some point.

When was your tank last cleaned? Do you know your water parameters? Darting and behavior like you're describing can occur when the fish is being poisoned by bad water conditions. Heat can be an issue. Have you added anything new to the tank lately? What are you feeding your fish? Could he have gotten a disease from a feeder fish?

Here's a site where you can discuss your questions with experienced aquarists who can hopefully help diagnose and treat your problem.

Answer 3

I promise to no longer lecture you on a thank you to maintain Oscar's, inspite of each little thing you have had him for 6 years.. i became getting to know the oscar relatives at present as i'm thinking installation a tank for some, on an analogous time as they seem to be very worthwhile fish to maintain various what i became interpreting became approximately weight loss plan, stay ingredients and tank set up. The weight loss plan section appeared to recommend that any 'meat' with a fat base like 'in simple terms approximately any beef' etc could be undesirable lengthy time era as is holds fat that the fish does not technique so properly in later lifestyles etc. And the tank section became conversing approximately in simple terms having sand and a few properly located rocks because of the fact the oscar likes to go 'furnishings' interior the tank etc, Like i say, i'm no longer attempting to lecture you on what has got here approximately, it is maximum possibly in simple terms getting older and the outcomes of a lengthy satisfied lifestyles. wish it gets extra powerful.

Answer 4

I dont have an answer, but i have a 14 inch oscar , and he does the same thing. He swims like hes lost his mind, out of no where. It is entertaining to watch. i dont think he is sick. As mine has been doing it since i bought him, 2 yrs ago when he was inch long.

Answer 5

I don't want to give you bad news but I had a goldfish a couple of years ago and he died a couple of days later.
You have to see if he pooping a lot if it is could be diarrhea. If its a gold fish look to see if it has abnormal spots on his skin for example white little dots that is one symptoms that he is sick. Abnormal swimming habits. If his appetite has changed. Anything that seems to be not normal for your fish is a sign that he is sick. I want to wish you all the luck

Answer 6

he's probably going to the top of the tank to gets some air. do you have a way for them to get bubbles air pump. But fish's are not in now its buying kids from other lands so i would go for that >

Answer 7

what size tank is he in?
i had to keep my 11" in a 25 (i know it's brutally cruel) for a while while i repair the 75 gallon(which he's usually in) and he went psycho untill i took him out and back in the 75 then he settled back down.
does he have alot of scars and stuff around his head? do you feed him alot of goldfish? it could be a syptom of HITH (Hole In The Head) disease.

Answer 8

I would suggest that its when you enter the room? if its on its own it does indeed need company, however just your face will do. They're very sociable and like nothing more than you to attend to them, they're the dog of the fish world.

Answer 9

Probably not, unless he ends up floating on top of the water...Unglue your face from the tank, and he'll be back to normal again...

Answer 10

put in a few other compatible fish to act as company so he doesn't feel like he's all alone. any single fish will do some strange things when they are constantly alone in a tank, regardless of type of fish. acting goofy is just a preamble to going fully nuts.
