First time poster here, hi everyone.
My beautiful half moon boy Zeus had a beautiful tail yesterday, a stunning fuschia pink with white edging half moon he was swimming gracefully, very happy and then today he has been in his cave all morning so I lifted the cave to get him out and saw that he is not able to swim properly upwards to the surface and then he went on the side and I noticed half of his tail, the moon part that joins the tail is missing and he now looks like a veil tail.
He is the sole fish, nothing else resides in his 5 gallon tank, not even a little snail, how could this of happened overnight?
My water parameters are fine, I am a very experienced tropical fish keeper with many tanks, but I have never seen anything like this before, especially so rapidly. I cannot even find the missing part of his tail in his tank??
Will it grow back? What is his future for survival? And what can I do to help him. I am so upset I am crying
Please help my Zeus. I will try to attached photos..
The 1st pic is yesterday flaring at a mirror. 2nd pic is of today
