Hello! I have had a lionhead goldfish for about 6 months now that I bought when it was just a little baby. For the past 2 days he has been floating near the top, not gasping for air or anything, just sitting up there swimming gently. He has no swim bladder issue, as I saw him swim down to the bottom of the tank today. He also has been getting a really puffy face lately with tons of small red dots around the outside of his face. I know a puffy face is normal for these fish, but what about the red dots and little activity. He seems more hungry when I feed him though. He is in a 55 gallon tank with a blackmoor and a ryukin, both bigger than him. Any help fast would be appreciated, as I am leaving to Edmonton tomorrow and won't be back for about 5-7 days!!
