I have a 35g tank that is 9 mos old. Original fish: 2 aulonocara stuartgranti (male and female) approx 3 in, 1 OB male 3in, 1 moori 2in. Added 3 yellow labs 1.5 in about 2 months ago. Added 2 bristlenose pleco 3 weeks ago from Petsmart. DUMB MOVE, I know! My male flametail started flashing about two weeks ago. Assumed initially that he was showing off as it was about time for them to mate again. Now ALL fish are flashing, itching, breaking scales around their gills. All the research I could do made me assume they have either gill or skin fluke (though I can't visualize). Male flametail is in really rough shape. He is staying at the top by the filter nose up for three days now. All the other fish are irritable. I started treatment with PraziPro Monday (80% water change with heavy substrate cleaning & removed carbon and ammonia remover from filter-aquaclear 70 HOB) with no signs of the fish getting better. Water is testing fine so far: Temp: 24.3 C, Ammonia 0, Nitrates 0, Nitrite 0, pH 7.8, Alkalinity 180, total hardness 200. Fish are struggling and I don't know what else I can do. I have never experienced this before and can only treat by what I can find on the internet. I started treatment with salt and slowly increasing water temp to no avail, so I started treatment with PraziPro. Does anyone have any recommendations on how to treat my fish and hopefully save them. I am so worried! I can't find anywhere on a smart or tried & tested way to successfully treat flukes in cichlids. All my cichlid friends have never had the unfortunate event of dealing with it because they're smart enough to NOT go to chain stores for a pleco! PLEASE HELP!
