Best food to medicate for nano fish

[Instigate]

Not sure if this belongs in the Aquarium Nutrition subsection or here.
I have a tailspot blenny that is being treated for internal parasites. What would be the ideal food to feed him that I can infuse with general cure/focus? He eats frozen mysis but being an herbivore I don't know if that would be adequate. I got the hikkari seaweed extreme s. He eats it but he plays catch with them to get them eating a small amount at a time. He loves the seaweed sheets and I was wondering about spraying a sheet with meds then letting it dry out. But I think that isn't likely to go well.
Is there a better food that is smaller, sinks, and is mostly seaweed? I also don't like how much these pellets break apart.

I've used herbivore preparations from LRS and Rod's Food, and love both. "Formula Two" is also a good formulation for herbivorous fish, and may be more available locally.

Thanks. I know a local shop sells lrs but idk if they have the fish food from them. They specialize in coral. I'll have to check.
