I’ve had a few clients with fish dying at this time of the year. It’s not surprising because it’s only now that the weather is getting cold in Perth. I suspect the dropping temperature is causing poor immunity, and secondary bacterial infections result.
What you can do to prevent this?
Check water parameters and biofilter are OK. Then add vitamin C (in water, or in food) and reduce osmoregulatory stress by increasing salinity to 2-5g/L.
Failing this, get them vet checked before we get into the really cold part of winter.
