OHHH.....

She was fine this morning but then I noticed that her dorsal fin was not erect as usual. When I got home from school this afternoon I went to check on my fish and everyone but her were fine. She is being lethargic and didn't eat anything. When I put my hand on the glass by her she freaks out and darts to a new hiding place. Her fins look fine. No impurities or discolorations at all, at least that I can see. Do you thinks she's just resting? I don't think its anything serious but this is how the marigold acted before he died. He became lethargic, wouldn't eat, became freaked out if my hand was near him, and then..... he died

(By the way I named my fish(The platy is Atticus, the Black Swordtail is Octavious, The Koi Swordtail is Diedric, The Male Cherries are Ghildolf and Henricus, and the female cherry barb is Eramus
