okay so how can this occur ? is it from stress
?
thank you neale again for all your helpWhat species of Takifugu?
Reddening of the fins is a common precursor to finrot, as bacteria block the blood vessels, which causes them to expand and become more visible. Check water quality and water temperature first, since these are of prime concern with Takifugu generally; also review salinity and alkalinity.
Cheers, Neale
