After doing some reading, it seems that using Binox as a PERCAUTIONARY measure on W/C rays would be a good practice... Just like Prazi.... Maybe I'm wrong but going back to the basics it seems kinda hard to doubt Ross.
For clarification Turkeys, and my rays are not from the same place, however maybe thier point of collection is similar....
My lil girl will raise herself up completely off the bottom of the tank, almost like she's assuming the eating possision but no food. Still refusing all worms.
Mine was also breathing REALLY fast up until the Binox dose 2 days ago, since then her breathing has calmed, don't know if it was from the Binox, or seperating from the other fish....
