twitching?

Post questions you have about keeping Oscars here.

twitching?

Postby Fox » Wed Jan 12, 2005 7:12 am

my O is twitching randomly in my tank. the impact from it is so big i can hear it. i've checked the heater, there doesn't seem to be a problem with it, or anywhere that might run a current through the water. when this happens, it's as though someone has just bumped up against the glass and she's reacting, but i can never see any reason for it, there's no noises or thumps in the house when it happens...she just suddenly, without warning or apparent reason, jerks. before and afterward there are no signs it ever happened, she doesn't seem to get irritated or anything. does anyone know why this might be?

i have also noticed that since i moved her tank into my bedroom, she's been swimming frantically against the walls of the tank, like she's trying to get out. she's alone in a 65 gallon tank, so i wouldn't think it was because she's cramped...she never acted like this downstairs before i moved her.

In order to get a better picture of what is going on with your fish and its environment, we need more information. Please let us know the following:

  1. Other fish in the tank?
  2. How long has the tank been running?
  3. What filtration is on the tank?
  4. How often do you do a water change, and how much do you change?
  5. Ammonia reading?
  6. Nitrites reading?
  7. Nitrates reading?
  8. pH?
  9. KH?

If you do not have one or more of these kits, take a water sample into your local fish store, and they will be happy to run tests for you. Please report the actual numbers. Different people have different ideas of what "fine" and "ok" mean. To help you, we need the actual results.



Could be that it's just adjusting to the new environment. Could be that you are having a mini-cycle from destroying some of your bacteria during the move. In addition to the questions above, how long ago did you move it?

the move was 3 days ago. she got about 10 gallons of her original 65 back, the rest was new water. the filter is an aquaclear 300, and i'd tell you about the levels but i seem to have misplaced my testing kit. with only a few days on the water, they should be fine. i would go get it tested at the pet store but since i don't own a car, it's a little difficult to get there. i didn't clean the filter out so i could be sure the bacteria would stay established.

would the cycling of the tank make her twitch? i've had her for about a total of 2 1/2 weeks, she was only downstairs for 2 weeks and she never did these things while she was down there, in the same tank. aside from her water, the only thing that's changed is the environment outside the tank.

no, i asked my LFS about it and they said all i would really need is the dechlor/slime coat solution, which i used.

I shouldn't worry too much about the twitching. Both my Oscars do it on occasions one more than the other. Obviously I haven't seen exactly how your Oscars twitch but I would imagine it is rather like my pair. Sometimes my male Oscar will do it quite a lot when he is cleaning rocks. He's done it for a long time and it has never bothered him so I haven't pursued the matter. As long as you keep your water in good condition and feed them a balanced diet then I really don't think you have anything to worry about.

As for your Oscars swimming frantically at the glass (I think that's what you said) mine also do that. I often wonder whether they can see their reflection in the glass and because they are not exactly the sharpest tools in the box they think it's another fish. Anyway, that's my theory.

alright, thanks, i was just worried there might be some weird explanation to why she would twitch and jerk like that, but if it's normal, i won't worry so much. maybe once i get her a mate i'll be able to tell if it's a mutual thing or if she's just a tweek. :)

I dont' know if this is the same thing.. but before we got our O's we had a 10" goldfish. It looked like he was having seizures (twitching and such) and then he would be just fine for no reason at all.. about a month after the twitching started he got a very severe case of Ich which killed him.

I would just keep an extra eye on the twitching fish ...

If the tank has only been set up for 2.5 weeks and you did not cycle it your tank is cycling and the twitching is a bad thing. Your LFS gave you incorrect information. I would recommend finding your test kit and testing the water for ammonia and nitrites to see just how bad it is. I would also do a large water change to dilute the toxins. If you can get hold of some BioSpira it would help alot too.

the tank was cycled before i put her in it when i originally got her a few weeks ago. i had a few other fish in there before her, i tested the water for levels and i did a 30% change before i put her in there, and the fish coming out of the tank were completely healthy. so...originally, yes, the tank was cycled and level. i didn't let it sit for any length of time after i moved it upstairs, but i didn't clean the filter and i only cleaned half of the gravel, so i could be sure there would be a decent bacteria base for her, and on top of that, she got to keep about 1/6 of her original water. no, the tank wasn't actually cycled after i made the move, but since the LFS said it would be ok, and i took the extra steps of making sure the bacteria base would be there and she actually didn't get much more than a eally drastic water change, it sounds like she should be doing ok. if i could just find my stupid test kit....but anyway, i'm not *too* concerned about the levels. the twitching seemed more like a non-water-related variable, which is why the first thing i did was check to make sure the heater couldn't be sparking or something.

Okay, I misunderstood what you were saying. It is possible though that the bioload has been increased enough to cause it to go through a minicycle and so I would recommend testing your levels anyway. If you can't find your test kit your LFS will usually test the water for you for free.

A fish "twitching" in a cycled community tank is a sign of dominance. That fish says "I'm the Boss! Bow before my might!" They are challenging the other fish, and usually this helps keep a pecking order established and violence to a minimum.

I wouldn't be overly concerned.
