I got a new dottyback on Monday and I noticed his color wasn’t completely there but I didn’t think much of it because I assumed it would get better. Well it slowly got worse in less than a day he died. He stopped eating and was rubbing up against the rock yesterday and started having this weird film I originally thought it was ick I now think it was velvet. He died. I just set up a quarantine tank I didn’t have one before. The dottyback was in my main tank for about a day before I took the little guy out. Sadly I didn’t have a quarantine or copper on hand and it happened at night and I think he was too far gone to save under the best conditions because he progressively got worse. Sorry these are bad photos but it took me forever to get and to get him out. I bought vitamins/supplements. I just don’t want to stress them out unnecessarily. Can I just wait a few months to add new fish and monitor my current ones? Do I have to quarantine for 76 days with copper and go fish less in my main tank?
