Hey all, I have new kuhlis and a few of them were looking skinny (i.e. head thicker than body). The fish store told me they were treated already. But I made the decision to dose them with expel-P. After about 5 minutes they all started crazily glass surfing the aquarium (in the day with the light on). Did I make a mistake? Or does this suggest perhaps they indeed do have worms and now feel uncomfortable because the worms are trying to pass? Would like some reassurance please - I'm worried about them dying from stress now. thanks for any advice/comments you can give.
