Hi, I have an odd question. I have a 20 gallon tank with Platys and Guppies.
All has been well for about 4 months. All of a sudden 5 fish die in a week. They all started swimming a bit funny and then looked a bit thin and curvy(??). The next day they were dead - this was over a period of a week. I checked the filter/nitrites/nitrates and all are fine. Water is changed every 2 weeks (only about 15 small fish in the tank). The temperature is at about 25. I ornament and 6 small plants in the tank. any help would be appreciated.
Thanks
