Hello, I am a newbie to this hobby but feel that my knowledge is getting much better due to constant research. I did post this in another forum, but was told the experts are here. I am very worried about my fish. I currently have a vol. lionfish, a harlequin tusk, dogface puffer, and chainlink eel. I had a clown triggerfish, but died yesterday
(he was my favorite). I have had them all about a month to a month and a half. They are all pretty small (about 2-3", and the tusk is about 5") They are currently in a 75 gallon that I turned into a quarantine tank which has a 20 gallon sump used for water circulation, volume, and O2. I am in the process of setting up my 200 gallon. The symptoms of the clown trigger and tusk are as follows: White spots (some raised) all over body, even on eyes, clowdiness around eyes (looks like cataracts), slow erratic swimming, laying on sandbed, heavy breathing, heavy slime layer on skin, pale coloration, and loss of appetite (which is very evident considering they were all very good eaters). The lionfish doesn't show much signs of anything, but is not eating. The puffer has white spots on him, but seems to be doing well. The eel is hard to tell... he keeps escaping out of the overflow syphen tube so I imagine thats pretty stressful in it's own, but does have the white spots. I spoke to my LFS and they said it might be ich and told me to dose the tank with .5ppm copper, so I did. It's been 3 days since adding the copper and their symptoms seem to be getting worse (hence the clown trigger's death). I am willing to try ANYTHING to save my fish. When I setup my quarantine tank, I removed a lot of the rock and frags/mushrooms and put them into a 40 gallon breeder so they wouldn't be harmed by the copper. The sump for the 75 gal. was also used as a refugium with live rock and algae, pods, snails, and crabs, but removed all of it due to the copper. Readings include: ammonia-0, nitrite-0, nitrate-20ppm, pH-8.2, copper- .5ppm. Any help would be much appreciated! I would hate to lose anymore of these guys. I have been reading about flukes and parasites, but not sure if that's what I have. I have not noted any worms on the fish, but have seen tiny wormlike things crawling on the rocks. I also have tiny white bugs all over the glass, but was told by the LFS that was a good thing... I just noticed little white spots (about the size of a needlehead. with 6 little legs. Don't know what that is. Thanks!
