I apologize in advance for making a post about a recently deceased fish but please help. (Sticky answers below)
This morning, my daughter's second betta developed swim bladder, yesterday he hid all day but swam around fine. Today he couldn't swim well and progressively got worse until tonight he died. His fins seemed warped and eventually completely clamped like they were hard and his color looked blacked, I will add a picture. He is a half moon betta but you can't tell now because of his fins.
Is is possible this happened because his water was too cold? Yesterday I had the windows open all day because someone was using a paint thinner type solvent on our couches to get sharpie out of them and it was quite cold in here. I KNOW I need to get a heater if we get another fish but what else did I do wrong? I really want to have a happy healthy pet and don't ever want to see one suffer.
Background: Daughter got a fish for her birthday, it was sick when given to us, developed white stuff on its clamped fins and body, didn't eat the entire time we had it, and died before the week was done. Link to last post: http://www.bettafish.com/showthread.php?t=116305
How do I sterilize the tank, rocks, plant and decoration without using bleach? Is it possible this one got sick with different symptoms from whatever the last fish had?
