I recently got a couple of African Cichlids for my tank and since then I have been having a parasite issue. A couple of my fish are flashing and scratching themselves on the rocks while others are not affected. The new cichlid has it the worst and clamps his fins and shimms often. I cannot find any evidence of ick and but I suspect it is velvet. I have tried raising the temp to 82 and using Cupramine but it did not work. Has anyone had a problem with parasites affecting the same host over and over? Anyway, any help is appreciated.
