I suspect internal parasites in my 35 gallon tank

[Fishmanic]

Lost a serpae tetra and have lost a few others in recent months. I noticed a white belly on them before they died. I treated the entire tank with prazipro but think I should also treat them internally through feeding. Should I diltute the prazipro before soaking flake food in it and then feeding to my fish? What concentration should I dilute it?

is anyone able to answer my question above?

Hi,
I don't think you should dilute it.
When the flake food is drop into the water, the water will dilute it.

In fact whenever I pour the prazi into my aquarium, some fish (Geophagus) will even eat the prazi that are not properly dissolved into the water.
And the on the following day, I would see the dead worm at the bottom of my tank.
My fish don't seem to be affected by the prazi.
Remove the dead worm on the following.

All the best.
