Lose of color in fins

[weird]

Have noticed or atleast I think I am noticing a loss of color in the fins of my pigeon bloods. I lost a Pigeon blood 2 weeks ago who had lost all of the color in the fins ... this guy had lost his appetite for about 1 week.

Nothing else is showing as a symptom with the other guys. No loss of appetitie or anything. I could be imaging it after the loss of the fish guy.

Water parameters have been stable etc, no change in diet.

Any ideas ?

Dave, at this stage I'd just increase those waterchanges and keep a close eye on the fish for any other symptoms.

Could be something brewing, but maybe not. Observation is your best course of action at the moment.
