I would say good to hear sorry I have not been able to respond sooner as I have been doing some courses. Watch your tank in about 2 weeks if it was flukes it may come back the cycle can very but 2 weeks is a good time to pay extra attention to your fish. Feed them the garlic extreme and selcon it help them build their a-mun system and prevent disses like hole in the head. Things are very hard to give a treatment regiment advise over the internet I have come across a couple sites that no one will answer these types of questions unless you can provide all tank test results and a pic..
