hello all, this morning i woke up to my oldest goldfish severus sitting on the bottom of the tank and almost on his side, right away i was worried, i added the correct ammount of melafix to the tank and hoped for the best. well it was to little to late i noticed at about 10pm that he was right on his side at the bottom of the tank, i also noticed that there was a little blood coming from his gills. i instantly grabed him and decided to end it. as hard as it was i took his head off, its the best way i have of doing this deed. regardless i had noticed a change in his appetite in the last week. but nothing that would trigger anything this serious. his dorsal fin wasnt always fully up but that wasnt anything unnormal. the only thing i could see was the loss of appetite. i feed my fish hikari lionhead sinking pellet. there is no ammonia reeding and no nitrite reading, well its the lightest colour blue i can tell. the ph is 7.5 and i use an emperor 400 and a 40 gal foam filter, marineland ammo,carb and rite size e filters. i will be watching my other fish very carefully over the next week. if anybody knows why blood would be coming from the gills when breathing let me know please, i had this goldfish for 2 years and it was 12 inches with tail i loved this fish. RIP severus
