Panther grouper question

[alddb]

We got a panther grouper. He was fine until yesterday. He is rubbing in sand and hanging around the top. He is refusing to eat.
But past two days , he ate krill plus a live feeder both days. Hoping this is why he is not eating.
this normal behavior? All other fish acting normal. No spots.

Recently I got a miniatus grouper that may have been doing the same thing. He was hanging at the top near a power head head and would do this bounce thing on the substrate. He stopped eating and I though it could be flukes, so I treated with prazi pro and he returned to normal ,

Is this only available online? I did a search locally and can not find any.

Are you talking prazi pro, it's a pretty commonly used treatment so should be available locally. But I also do get it on Amazon.
