We have been very unsuccessful in keeping our goldfish alive. We have lost 8 fish in about a month, much to the distress of their child owners. Our tank is 14L and is well filtered and oxygenated. They have gravel and live weeds. We are very careful with the amount of food we give them, do partial water changes every 2-3 wks and use water condition and stress coat to keep the integrity of the water. We lost 2 fish over the wkend after owning them for 5 days and our remaining fish is floating/swimming upside down and has white spots and a droopy fin. Does anyone have any advice to help us!!!
