hi i have 2 oscars in a lge tank with plecos and one of the oscars is going round and round and up and down in tank spinning as he goes he has lost his black colour and gone grey over last 2 weeks does any one have any ideas he doesnt fight with other fish at all dont think he is in stress cheers

Have you tested the water to see if there's anything going on there?

yes water is fine have shifted him to hospital tank and he busy spinning around

No sign of damage? It is possible they fought and he was rammed in the side so has internal damage.

perhaps he swan into the side of the tank??

he may have damaged internals not sure but if no better sunday its of to fish heaven i think

i recently read about this happening to a person on an oscar site i moderate, it seemed really wierd. it spun around the tank hitting stuff, would lie on the bottom breathing heavily and then do it again and then just died (all within a few mins i think) :-? it had been totally fine up till then, no signs of anything and i think the consensus was that he had some sort of internal failure or it was just going to be one of those things where you never know, poisoning was also mentioned but other fish would be feeling it if it was that i would think. i thought perhaps some sort of nerve damage etc as they are tough beasties and if they hit the tank hard enough they could knock themselves out or damage something internally. but seeing as your boy is still alive and keeps doing it i am unsure what it is

heres the post to that anyway, it might be of some help- http://www.theoscarspot.com/smf/index.p ... 080.0.html

good luck with him, i would do some water changes just to make sure its not water related. is he eating still?

no he stopped eating but looks better today a bit darker in skin and not so much spinning but still not him self may be getting weaker have to wait and see cheers

Could of been a head knock. Same sort of symptons.

what does he eat usually?

garlic is often used to help fish get back to eating again, apparently they like the taste, perhaps if you put his food in some crushed up garlic for a while (roll it round so it gets garlicy) and offer him some. my oscar loves earthworms so perhaps that might be worth a shot trying to tempt him? oscars can go for a month or so without eating but it is a concern when they stop so its best to get them started again if possible.

lets hope he improves and its not him getting weaker

sad to report i have only 1 oscar now thanks for info and feedback cheers

bummer- it aint nice loosing fish but fish like oscars are even worse *hugs*

seems like one of those wierd things that you will never figure out

Sorry to hear
