Strange white string in Rainbows mouth

[jmarcf]

Hi

Not sure how to describe it but I have a fairly new large female Murray river rainbow (6 rainbows all up) that keeps trying to backflush it's gills and this white stringy looking thing comes out of its mouth. I had seen it a couple of days ago coming out of the fishes gill.

I doesn't really look like a worm or anything alive but a piece of the fishes tissue or something. Now it could be a worm but it is hard to see because the fish is swimming around and it keeps going inside the fishes mouth. She is eating and acting normal apart from the swimming backwards to backflush her gills.

Does anyone know what this could be?

I'm thinking of netting her and try to pull this thing out of her mouth. Is this a bad idea?

Thanks

Any more details? Any flashing?

It is both sides, solid / wispy, ?

Anything change in the tank a few days ago?

Hi

Sorry should have added more info. No flashing at all, wispy almost like one of the Rainbow eggs is caught in the gill/throat/mouth. Nothing has changed in the tank at all

I'm sorry, that's a new one for me if anyone else may know.

Edit - couldn't be fungal at all?
