Well someone I know who keeps a bunch of rams told me that mine look ok. That when they are in trouble they will not maintain colors as vivid as mine and to wait before treating with anything else. I feel like that is good advice and will follow it.
In regards to the levamisole side effects I was researching it. In humans the majority of side effects are caused by the evacuation of the parasites not by the med directly. So organisms with heavier parasitic loads will be hit harder.
But I will be dosing nothing in the tank and just observing dor a few days.
