Well, my poor fish I just got on Sunday died yesterday evening. :/ I think he must have been ill when I got him, though he had no visible signs of illness until right before he passed away.
I knew the store had a 14 day guarantee on fish, so I called to see if they had any Crowntails left. They did, so I decided to go ahead and try once more with a new fish.
---> Before bringing the new fish home, I cleaned the tank out with extremely hot water to kill anything harmful that might have been there. I now have my 2.5 gallon tank set up with water treated with Betta water conditioner, and a small heater and the temperature is a steady 78 degrees. Also the pH is a solid 7.
This morning though, I see the water is cloudy white. I looked it up and it seems to be a Bacteria Bloom. I changed 30% of the water this morning before leaving the house (for work). Topaz -my new fish- did not eat this morning, though I am trying not to worry about that at this point. He *seems* healthy, though the fish I had before did too...
I've read that a new set-up tank can have a Bacterial Bloom and that excess fish waste can cause the bloom. There is no waste in the tank though...
Is there anything I need to do? I have never had this much trouble keeping a fish alive. It's worth mentioning I've never used a heater either, though I wouldn't think that was the cause it does make me wonder.
I have no aeration, I have never used that either. Never needed to. Shouldn't 2.5 gallons with daily partial water changes be sufficient for one Betta?
I really want my new fish to live. So, if there is anything I need to do please let me know. I'd hate to think I am killing fish. :/
Though, if he does end up dying like the other fish, I plan to just get my money back and never buy any more fish from that store again (Petsmart).
Thank you all for any help. I want Topaz to have a longer life that his predecessor did. :(
