Discus sluggish after worming

Hi, I recently dewormed my juvi's the are between 6-8cm , I used 1 dose of prazi 19g/L and levamisol 38g/L.
Doseage 1ml per 10 litres, I aerated, and did a water change on day 3 of 50%

Thru the process they have not been active, and even after the water change they are all just hanging around a large bit of driftwood.
If I put food in the tank they come racing out and munch it down then go back to around the log.

Any thoughts?

Levamisole will do that. They should rebound in a few days...

Oh that's awesome, thanks, was getting concerned.

Levamisole actually does stimulate the immune system. They use it in cancer patients for that very reason. But before the immune stimulation kicks in it makes the fish lethargic for a couple of days.

Great info thanks
