Isopod......I think????

[RBU1]

OK so my female crosshatch has been in QT since May 2nd and cupramine ranging from .25 to .50 since May 12 (don't ask about the fluctuating copper level)....anyway there is a thing the size of a large grain of rice attached to her top fin. I had a friend come over and look at it and he thinks its an isopod. It has a nice oval shape to it and is gray in color. It never leaves the fish.....Even when the lights are on. I thought copper would eventually kill it but not sure whats going on.....Anyone have any expierience with these things? What can I use to get rid of it???? I can't get a picture to come up clear enough so a picture will not come out...

I've never dealt with those myself. If it is big enough you can manually remove it.
I would have thought copper would have killed it as well, how long have you been medicating? Another thing worth a try would be a freshwater dip, as most inverts don't like changes in salinity.

Keep up updated on what happens.
