Looked in the tank tonight while doing feeding round and realized our little red girl was looking a little odd. Her left gill is swollen and her face is noticeably deformed. I'm pretty sure she's been okay the last few days, but we rarely see that side of her face because she's always either facing the divider (on her right) or front of the tank, so all we ever see is her front and left side.
Her gill is normal colored, and she's acting completely normal - generally just being nutball and a bundle of energy. She jumped out of the water for dinner as normal and her and her man are doing their normal "love you - hate you" dances through the tank divider. He's looking and acting completely normal, too. She's about a year old, we've had her since she was a 3/4 inch long, and she's never had any issues. Tank is a cycled 7 gallon with normal water parameters that's been set up for two years. She was the last new addition to that tank and the other fish in the house are completely normal.
Is this something I should be concerned about? Anything I should be doing to prevent something worse? Is there a possibility that it's a tumor rather than a parasite or infection?
