White Spot....but Only On My Loach?

[Tiger Tiger]

I am in the process of dealing with white spot. now half way through the process most fish are starting to look ok.
But my 3 clown loaches are covered in it with no sign of leaving?
My 3 Catfish are ok so i do not think its them dwelling on the bottom catching it again.

Can i just confirm with others that i use Prozin at 1 drop per Litre. On days 1,2 and 6?

Is white spot attracted to loaches more than most. Is it to do with having no scales?

Thanks in advance.

If Loaches are present only use half doses of Protozin, you can though add half a dose 12 hours apart so that they are still getting the full dose in one 24 hour period just not all at the same time.

I have had more success using Myxazin to treat White spot on Loaches using the above method of adding a half dose twicw a day 12 hours apart.

Clown loaches in particular do seem more prone to bouts of white spot than most fish.
