Mr's. Hemdel/Vetteguy, 2 part question, I lost the Bellus that I had about 2 weeks in QT. It was eating great until the last 2 days then stopped and was breathing heavy. I was treating with copperpower thinking it was ich with no improvement. After it passed, I used 5X magnification and noticed quite a few small critters crawling on its body so suspect it may have had flukes. I would think the copperpower would have killed any invertebrates so that why I was thinking flukes. My question is, how do live flukes react once a fish has passed and could I see them using 5x magnification? I froze the fish and will get a Microscope in the near future. My other question is about Quarantine. I have 2 Tangs in a separate 40 Gallon that began on Dec 19th. They had flukes which I successfully treated with Prazipro. I have been observing them for ich, etc. since the beginning and have seen no evidence of anything else. I periodically run a 25 watt UV with low flow on this 40 gallon QT Tank so did not perform a copper regimen. Since Tangs seem to be ich magnets I'm thinking I should be ok to transfer them to my DT sometime this week or would you guys recommend turning the UV off and running Copperpower? Both seem very healthy and the Purple Tang is growing like a weed.
