So my native stream tank has a case of ich. What should I do? I had the wife pick up ick medicine today but I have not used it because I'm still at work. I just noticed it last night after temporarily holding them in a feeder tank while I cleaned the stream tank out.The tank is a 36 gallon stream setup with southern redbellys and darters. I have only noticed the spots on the redbellys. Any help appreciated

Another thing is I had a few darters die in a 24 hour period. That's why I decided to do a 100% water change. The nitrate level read high at around 80. (Used test strips) This is the first time I have add any trouble with my native tank. Do you think the nitrate level killed them or was the ich already running it's course? One darter I could not save was very red around his gill plate when I found him.

Back off on the treatment regimen. As described it is a stressor in its own right and can promote ich outbreaks. High nitrate in an aquarium often correlated with other high waste product levels, particularly organic compounds which can support increased abundances of disease organisms not including ich.

When you say red bellies I assume red belly dace. My preferred method for handling ich outbreaks in warmwater fishes involves raising temperature into the lower 80's F. Water changes can be done at same time but avoid over doing it. With stressed fish avoid swapping out more than 10% each day and be sure to used properly aged water.

Increase aeration and consider the addition of salt raising it to about 1 ppt. Since already isolated, consider using an antibiotic. Antibiotic does nothing for ich but helps control secondary infections which are generally the biggest killer once ich infection gets underway. Since red bellied dace, watch how they handle elevated temperatures as you will be approaching their limits as well.

Just a little note, certain cyprinids (minnows, dace, chubs etc) male fish develope spots (tubricules) on their heads when breeding that might resemble ich spots. Just saying....
