... nose down on bottom and top of tank today. I've kept goldfish over 10 years now. Can't seem to figure out how to keep it upright in the tank. It gets tired of struggling and gives up on swimming. Nearly stopped breathing a few times. I've put it in a small breeder, it's tail doesn't fit and nose is almost against the front. Can I keep it in the breeder overnight? ...what will happen if I do? (Small plastic breeder really meant for breeding guppies)...please help! Have had SunFire almost 4 years and was pretty big when purchased
