Afternoon all, hope everyone had enjoyed the Easter break. Been having a few problems with my tank. Purchased two baby platys from a lfs and lost both within the week. Tested water and all parameters are fine. I believe they may have brought something into the tank unfortunately. Noticed a few grains of white spots on my orange and black platys on Wednesday and with flashing behaviour from others. Treated tank with esha white spot and gdx. Day three for the treatment was yesterday. My red and black platys have picked up but my Hawaiians are still not doing well. Resting on bottom of the tank, rapid breathing, clamped fins, still flashing. Started using esha 2000 in case of secondary infection. Again water parameters are all fine, no spikes. They are still feeding ok but then go back to resting on bottom of the tank. Also noticed white tiny specs on glass but I am assuming these are pods. Shall I continue with the esha 2000 or any other recommendations please?
