Woke up this morning and just found Violet and Jade Both floating at the top of their 5 gallon tank. After all this, my youngest child starts screaming that his new dwarf hamster is dead. I have never lost a new Betta so I am very upset actually have never lost a hamster either as we will have had my daughters hamster 4 years this summer. Tested the water and got a reading of 20ppm on the nitrates which surprised me. I know that is not really that high but it should be zero, correct? I also did a proper acclimation procedure. I have three other Bettas all male so I am not sure what happened except that it had to have been the nitrates.
