Hi, I’m looking for help with my goldfish. Last week I bought 3 fancy show quality orandas. I put them in my 20 gal quarantine for a week and noticed nothing wrong. I was planning on quarantining them for 2 months. I have a 125 gallon tank that was doing a fishless cycle and would be done when I finished their quarantine. My 20 gallon cracked when they were in it and I felt unsafe putting them in the cycling 125. They didn’t appear sick so I dumbly put them in my 50 gallon grow out pond with my 3 baby goldfish to wait for my 125 to finish. My new orandas had white stringy worms coming out of their heads the next day. Crap. I did my research and I learned the the bio load would be very small compared to the tank size. Bear with me. I moved my sick orandas into the 125 and stuck with very frequent water changes (50% every three days. The ammonia has stayed at 0 as have the nitrites) and I medicated them with. Microbe-Lift, Herbal activities, ARTEMISS. Which did nothing. So I read to treat with MELAFIX. My main questions are: should I switch to melafix? is melafix safe for my young fancy goldfish that came in contact with the infected fish? (They are about the size of extra large grapes) and how long should I wait to treat with melafix after I’ve treated my orandas with artemiss.
