Hello everyone, I'm new to the forum (and goldfish keeping for that matter), so forgive me if there's some stuff missing in this post. Me and my girlfriend have 3 commons and one sarassa sitting in a 220 liter tank. We got them less than a year ago and they seem like they are happy we got them :-). Recently we went abroad for a week and once we got back I noticed our biggest fish (Bradley) was missing some scales. Now he's always had some missing, growing back as well. But the patches seem somewhat larger this time what got me worried. They were showing some signs of breeding behaviour and I recently found some eggs as well. Water quality is fine, I do 50% water changes every 2 weeks and they get a varied diet. Flakes, floating and sinking pellets, frozen bloodworms as wel as some fruit or vegies now and again. No other special treatments except for Sera Goldy Aquatan when I do the water changes. It might be noteworthy that they're not behaving any different as they ever have before. Should I be worried and give them some treatment or do you guys think they just lost the scales due to playing around? Many thanks in advance!
