I went through it a couple weeks ago, but now seems to be under control.
Added a QT’d PBT to my tank a month ago, already had a Gem in there alongside a few others. I always suspected I had ich in the tank. but none of the fish had ever shown signs as I feed a variety of foods and supplement with Selcon and Vitachem. Unfortunately, the PBT started showing spots within days.
I don’t have space for a QT, even so, treating all my fish and going fallow for 45-72 days wasn’t going to work as I travel a good deal.
In order to manage:
- Did a good deal of research, and was led to this thread on H2O2 management on Ich. Gathered supplies to start ramping up dosage.
- Added a UV Sterilizer about 9-10 days into H2O2 treatment
- A couple days later added a Biota Cleaner Wrasse
The PBT was really the only fish to be hit hard, but a couple others started showing some minor spots along the way (I freaked a bit when my Conspicuous started showing spots). Thankfully the H2O2 dosing seemed to begin to reduce the number of trophonts on the PBT, though it still looked like a teenager with bad hygiene and whiteheads.
Adding the UV during the second week seemed to accelerate progress as I ramped up to the full H2O2 dosage for week 3. But, by this time the PBT was beginning to rub against the rocks, it just looked uncomfortable in general. All the other fish were largely doing fine, but I was determined to get the PBT in a good spot.
So, on a whim, I ordered the Cleaning Wrasse. It arrived two days later and immediately got to work. A couple days later I ramped up to full treatment. Now, I know cleaning wrasses don’t cure ich, but I seriously believe that the cleaning service really improves everyone else’s comfort and quality of life (which hopefully reduces stress for them to fight off the parasites). The wrasse literally dedicates its time to ensuring the PBT is spotless all while servicing everyone else. Easily, my favorite fish in the tank right now.
All fish are spotless and visibly less stressed, 23 days into treatment!
