I think my husband just killed our betta without knowing.
I set out some water last night with conditioner as always and asked him to change the fish water this morning. I came out to the kitchen and found Nemo swimming erratically, attempting to jump out of the water, sinking to bottom and then quickly jumping to the top.
I asked my husband what he did, as this never happens and I do 75% water changes with no problems in the past. He said the water felt too cold so he added some warm water.
What do I do? It's been about 20 minutes and he's seeming to calm down a little bit. He's approximately 3 years old, and my 5 year old daughter is crying that her Nemo is dead.
I did add a little cool water (not cold, but from a bottle of room temp water). He has seemed to settle down a bit.
Note to self: Do not ever let husband change water again
