76 days fallow 1 of 6 fish show ich symptom after being in DT for 2 weeks.

I really dont want to do another 76 days of fallow, are there any treatment that can boost the resistance rate to ich for a single fish?

Feeding them is usually all one needs to do but few seem to actually feed their fish a healthy amount.

The question is why one fish has it after 76 day fallow period? Did you treat those 6 fish, if so, how? I would think that you missed something along the way there.

2 1/2 weeks of cupermine with all 6 fish in the same QT.

Edit: Fish, purple tang, powder blue tang, 2 clowns , two blenny.

Only powder is affect currently. +-

Did you transfer to another QT at least 10 feet away after the 2 1/2 weeks? If not, you need to do 30 days consecutively AT therapeutic levels for copper to be fully effective. If youre doing water changes in the QT the copper needs to be added before adding the fresh saltwater to the QT.

Feeding to me is a band aid. Yes proper nutrition is very important and can potentially keep your fish managing ich but IMO its easy to take preventative action that can save the lives of the animals we care for.

My QT process has been really simplified from when I first began. I do 15 days at therapeutic levels of CP or copper, transfer to an entirely new QT with all new equipment at least 10ft away, wait another 2-4 weeks then add to the display. I have a small 40 breeder for all new coral, inverts or anything other than fish, wait 78 days then add to the display. It does take a little patience but the payoff is there when I sit down and enjoy my display.

Powder blue is likely to show symptoms first. They have a very thin slime coat. Keeping an acanthurus tang long term in ich management is likely to not end well.

A couple weeks in copper is not enough time to erradicate ich unless you transferred the fish to a second sterile QT during treatment.

Your DT was clean after 76days, so it's likely there was a viable tomont still releasing free swimmers in your QT post copper. Ich doesn't cycle very quickly.

Could you have a goby or something very tiny that you forgot you had? I've heard of people finding a fish hiding that had been long forgotten about. That would be the carrier.

Literally the same thing just happened to me. It's so annotina, but I'm just gonna run fallow again and deal with it. Better than losing $1000 worth of fish

Good move Brandon, this is what the OP should be doing as well.

As for the folks that are transferring to a second QT tank: why?. Would not the fallow tank theoretically be providing the same environment (with respect to Ich) as the 2nd QT?. it is unnecessary, if the correct concentration of copper is maintained. After a week the parasite falls off the fish and move to the substrate, after which they hatch and actively look for their next host. It is specifically during this stage that copper is effective.

I agree something was missed during treatment. Perhaps calcarous substrate or decorations were used, water changes performed without replenishing copper, less than 10ft from display, or insufficient copper level in quarantine.
