Fish Flicking To Briefly Rub Against Stuff....

[Miles_hot]

My tigers have started to show a new behaviour - at increasing frequency they are doing a sort of flick / half turn to briefly brush against the sand / rock / plant. Two are head standing (see my other post) however there seems to be little information on why they might be doing this (anything from poor water quality - tested good - to mating behaviour). We're just getting stressed by this as we had a dead tiger yesterday...

Having a panicky look around there seems to be any number of possible causes for fish to be itchy - is there any procedure / checklist / things to look for to work out what it is before I start chucking chemicals at the tank in a random attempt to solve the issue? We can't see any white spots.

Just to complete the picture we have dwarf chain loaches and 2 Kribs (with 10 babies) in the tank...

Thanks

Miles

the flicking tends to mean some sort of irritation the only time i ever had this was years ago and it turned out to be white spot

Ammonia and Nitrite both 0, Nitrate 20.

Any chance of recently done a water change with overdosing of dechlorinator?

Did a 50% change using buckets and I suppose I might have ended up putting as much into all the buckets as I would for the whole tank (spread across all the buckets) but I guess that wouldn't be an overdose ...

Looking through various tables on the net could it be a fungal infection? Would possibly explain the head standing (swim bladder disease) as well as the itchy behaviour ... ?

mine are doing that and I have white spot I am treating in the tank. Though they arent showing it. I wondered if it was either the meds I am treating the white spot or the start of white spot. though some have been doing it for a week and not showed signs of white spot.
