I have a 40 Breeder, moderate to heavily planted. Stocking is 5 Honey Gourami, 4 Hillstream Loaches, and 10 Cherry barbs.
I bought 6 of the cherry barbs from Petco about six weeks ago and quarantined them in a separate 10 gallon for a month and used the quarantine trio. They were healthy and active the whole time, with lots of chasing. I added them to my display tank last week, and the next day they showed white spots that spread to the other cherry barbs, so I started dosing Ich X. The white spots never spread to my gouramis and loaches, who have been acting normally the whole time. Meanwhile, the cherry barbs are hiding in a corner with clamped fins and white spots and ignoring food, as shown in the attached images.
After a week of dosing Ich X 1 tsp per 10 gallons and doing 30% water changes every day, I'm wondering if this isn't ich, especially since my other fish have no spots and are acting normally. Any thoughts?
Parameters:
pH is 7.5, ammonia and nitrite are 0, nitrate is ~5 (usually higher for my plants, but with all the water changes it's really low), temp is 75.
