I hope one (or two or three) of you learned people can help me. My daughter has had two fantails for about 3 years and a couple of days ago one of them started to swim in a weird position. It was like his skin was on too tightly on one side, so he was forced to bend to the other side. I thought he was on the way out, but gave him a few days to try to get better. Amazingly enough, this morning he was swimming almost normally, but listing to one side slightly. Anyone know what this is? I'd sure appreciate any suggestions you have. I clean the take regularly and change the filter in the water wheel regularly.
Thank you so much!
