Blue Tang

[Michael_B767ATP]

Hi,

I have a Blue Tang that developed white spots about three weeks ago. I removed all fish to a Q/T after a freshwater dip. I've been treating with Cupramine ever since the outbreak. The white spots were gone in a day, he has been fine until today.

I noticed today that he now has black spots on one side of his body. Since he is in the Q/T with Cupramine what can this be?.

Should I remove him from the Q/T that is being treated with Cupramine?. Should I stop the Cupramine treatment?.

Cupramine level in the Q/T is 0.5 ppm-mg/l

He is in a 30 gallon long tank with 10 gallon water changes every day.

==========
My tank levels
==========

Ammonia - 0ppm mg/L

Nitrite - 0ppm mg/L

Nitrate - Between 0ppm mg/L and 5.0 mg/L

Copper - 0.5 ppm-mg/l


The fish are being fed New Life Spectrum Non-Medicated Anti-Parasitic 1mm Sinking Pellets treated with SELCON.

Thanks
Mike

Tangs can develop black "spots" from stress. Keep an eye on it. It might move on you to a different spot. If that's the case, my bet would be that it is stress. IMO
