G'Day All,

Hoping you can lead me in the right direction.

I've lost a couple of fish in my community tank, all patients,
devoloped a light spot on one side, followed by a curving of the
spine, clamping on the tail fins, (they don't fan out wide) they then
become extremely skinny, before dying.

They don't appear stressed, and as soon as I see the tell tale signs
that fish is moved to a hatchery (but still inside the same tank).

All readings pH, nitrates, nitrites, etc are all within spec.... any
ideas?

BTW this is mainly Platys & Mollies that are affected.


thanks,


Ben.

My experience with platys and mollies has been that they will often get
crooked spines as they age, and they have very short life spans. You
may also have a parasite problem and low KH (which will affect live
bearers in particular). Make sure your KH is above 80 ppm. I would
recommend Medicated Wonder Shells for this as they add needed calcium
and treat many mild to moderate parasite problems (do not use them for
severe problems, use Quick Cure).
