Thanks, unfortunately the fish has died today. So wont unfortnately get chance to try that treatment option. Will of course keep an eye on the others to see if anything shows and definitely not going back to the shop I bought then from
Hi everyone, first post here as I amgenuinely lost with this challenge. Approx 3 weeks ago bought a shoal of black emperor tetras. One died within 24 hours, but one other has been permanently ill since. Within two days this fish in question developed white spots, which looked like a classic case of white spot. Therefore I have treated for the white spot. However I have now completed two full treatment cycles, and this one fish persists with one or two spots. It has not affected any other fish and this one black emperor tetra also hides all the time and is badly discoloured.
Despite the appearance could these spots be anything else?
