Thanks for your advice, I definitely wouldnāt have known a lot of that.
He's been euthanized and I buried him in the backyard.
Iām a hs student so half the time itās been my parents taking care of them, but Iāve been diverting more attention to them since quarantine. All weāve ever really done is feed and clean, and we have never known much about fish diseases and treatments, nor have we noticed them before. Sorry if I came out sounding sketchy when I said ārookieā ;(
I guess itās a fluke or something that heās lived this long. I will be sure to ask asap next time if I think a fish is sick.
I was wondering if I could clarify a few things though:
1. If I change 75% of the water, will it kill my other fish because theyāre not used to it? Before this all my changes were typically 20 to 30%.
2. To get the chlorine/chloramine out would that mean I should add aquarium water conditioner to the new water before putting it into the tank?
3. Do you have any ideas as to what he might've had?
Thank you and everyone else in this thread who lent their help
