Urgent : koi female betta losing scales

[Tyler777]

One of my koi female bettas is missing several scales. In the pic if you look at the white parts on her body n head , there used to be scales in there.
My wife zoomed in with her phone n kinda looked like her scales were taken off like an attack or something.
Anyone has any idea of what can be ?

Tankmates include 4 other girls, neons, corys, yoyo loaches n one 4 inches pleco.

She is also not moving much, not eating n goes up for air n then goes down to the bottom n stays there for a while

I encourage you to separate the girls. All sororities eventually fail unless the fish were from the same spawn and never separated. If not, they get picked off one by one until you are left with one.

Totally agree even though I don't do Betas. Betas are predictors even though they don't look the part. They are also very territorial. You just can't keep a group in the same tank.

If you had a tank of 2 hundred gallons you could probably get away with multiples but even a 30 gallon tank is really too small for multiple betas.

Can you post more pictures...

It's difficult to differentiate what is in front of the fish from it. Different views would help.

But, what is that white stuff on the gills and head ? I sure hope it's on the glass.

These are better pics. She is not letting me take better pics than these ones

Ok, now we can see...

She's been fighting, It would be a good Idea to follow suggestion to separate them.

Once it begins, it never stops until one is dead and then it moves to the next weakest one.

I put her into a different tank until she gets better. Then I will see what to do with the rest of them

Good. But I suggest coming up with a solution as quickly as possible. As soon as you move her out, a new target will be chosen.
