Thanks Whitney!

This is a copied post from Deb's Waiting Room thread:

This saga contiues and now I don't know where to direct my questions - here or in the emergency room?

Yet another fish is looking ill - one of my biggest, healthiest Platys. She stopped eating yesterday, is sluggish and hiding on the bottom and doing a lot of open mouth breathing. Those are the only signs so far.
I moved her to the HT and started Kanaplex 1/2 dose (hard to dose for a 6 gallon tank). So am I supposed to dose with a 1/2 dose for 6 days straight and then that's it? Can you do additional rounds ike with MI and MII?

Also, I checked for velvet and see nothing. Should I add rid Ich+ for good measure? Can you use Rid Ich with Kanaplex?

Thanks!
