need help with disease identification

[yoavbz]

Hi,

I've got 15 clowns ranging from small to 20cm+, 4 Pakistani loach and 40 Tiger Barbs in a 500 liter tank.
Few months ago one of the clowns lost some scales, shortly after it another clown lost some scales too.
It appeared that the scales are growing back but than one of them lost more scales and looked bruised.
This situation continued for at least two months, they ate regularly and looked very happy...
about two weeks ago I noticed that some clowns developed ich, shortly after it I saw that many clowns got dialated pupils.
I started ich treatment with Punktol (http://www.aquaristic.net/jbl-punktol.html?lang=1).
After 4 circles the ich got much better but the scale lost, Dialted pupils got worse.
Also some loaches developed clouded eyes.
I went for broad range treatment with ParaGuard (http://www.seachem.com/products/product ... Guard.html).
On the 5th day of ParaGuard their is no ich, the scales looks a bit better ( I guess recovering scales is a long process) BUT - no change with the pupils situation.
Ammonia 0, Nitrite 0, happy eating loaches...

What do you recommend ? continue with ParaGuard? switch to antibiotics? anythig elese?

Thanks,

Yoav

Hi yoavbz, welcome to Loaches,
Did the dilated pupils start after the Ich medication? Perhaps as a reaction to the meds?

[yoavbz]

I don't do nitrate readings as a common practice, the few times I checked it was low.
About 15-20% per two weeks.
I introduced new mangrove roots few months ago, they were boiled but could they be the reason?
No, the situation with the pupils began before the medication, I had good experience with punktol before - no side effects.

Thanks
