So, my betta "Crown" died today from Ich. Second one in a month. They were not in the same tank ever, and they were taken care of no differently than the two bettas I have. The two that are still alive, have never had Ich, and are very healthy. I do my 50% water changes every other day, or twice a week, depending. I feed them every other day, and always make sure to dechlorinate the water. Is it the store I bought them from? I bought both of the ones that died at the same place. The other two were bought elsewhere? Am I doing something wrong? All of my bettas are in 1 gallon, non heated tank, but the warm area i keep them in keeps the tanks at 74 degrees. They don't have filters, but I do water changes to keep ammonia out and have been successful. The two bettas that are alive I have had for almost a year, never changing the current conditions other than the water changes. Is this my fault that my newer bettas are dying from Ich? Or am I having a bad run? I need answers. I am no afraid to buy another one cause I dont want to kill it.
