So, April 1st I introduced 2 new fish to my DT from I highly reputable retailer that performs QT with treatment. I added a juvenile emperor and a long nose butterfly. Both were vibrant and eating within an hour of being added. In January I had an ich outbreak and lost my lion and pink faced wrasse. I treated for 30 days with cupramine before I did any water changes and added cuprisorb. Everything was going well until Friday, when I noticed my trigger itching. Last night the hippo tang had some signs...this morning the trigger and angel are covered. Since I have already dosed my DT should I just begin treatment again? Thanks in advance!
