Hey guys. I setup a 29 gallon established tank 10 days ago and have been monitoring the fish very closely ever since. Today I woke up and noticed that the yellowtail damselfish had an inflamed left gill :(

Here is a picture: http://imgur.com/gallery/GRsZL4r/new

Is it the dreadful ich? How would it get in the tank if I did not add any new live rock or livestock!!?? I have made four 20% - 25% water changes in the last 10 days and have checked the parameters a ton of times. The nitrate levels are high sitting around 50ppm but they were far worse in the condition that I received the tank in. I have also noticed a tiny white speck on the male clown which went away after a few days, and I also noticed a white speck on the female yesterday which went away in under a day. I have tried so hard in providing a better environment for these fish but it seems that tons of problems have arose after the move :sad2: I have been using premade saltwater and ro/di water from my LFS to provide the best water parameters for the fish but it seems I have royally ****ed up in some way. Help guys. I feel terrible.

hey guys thanks for the responses. I have checked ammonia and it seemed to be 0 or very close to 0 according to the "poor" api tests. I actually asked for others opinions on the ammonia test and they agreed. I have done 5 water changes in the last 10 days so I was very surprised to see problems start to arise in the last day or two.

I have now quarantined the fish and have begun a copper treatment. Will be doing 25% water changes every 3-4 days depending on the ammonia and nitrate levels. I am prepared for the 10-12 week long-haul now in case it was the ich...wish me luck.

Btw...where do you think the parasite came from as the fish were supposedly fine for 2 years before I moved the tank?
