Please help! Goldfish eye filled with blood. Urgent.

Hi!

I’m in desperate need of help. My goldfish is a telescope fancy. He seemed fine last night. He now has dark/blood filling his eye, not just the pupil but the entire telescope bubble. What happened? Can I treat this? He’s always swimming funny, settling upsetting down and breathing fast.

Thanks! g

Just put it in a quarantine tank with nothing that can injure it and give it a few days to see if it heals.

I'm no expert but from my research it may be from a fight/injury, but if he is the only goldfish then that's unlikely.
Goldfishes get eye sores, bulging eyes from bacterial infections...
Definitely quarantine your fish, and if you were to get a new fish/set of fish, clean that tank very thoroughly.

Also dont hold fishes out of water as it might cause injury or stress even more, just put it in QT tank and do 75% water changes everyday he'll be fine.
