Clownfish lost tail overnight.

[19Mateo83]

I’m sure I’m not the only one to have had this happen to a clown fish. Yesterday he had a tail, this morning no tail. There is no other fish in this tank. He is a recent addition. He was very active until this morning and is still fairly active. He is favoring the top of the tank now. Breathing looks ok, eating is good, no other mucus on his body, just on the tail. Water Parameters look good. Is this brook or bacterial or fungal. Considering this happened over night, Can it be cured in time for meds to get here? My LFS dosent carry formalin.

Day 7. The little clown is in good spirits. His fin is starting to grow back and he has a voracious appetite. He is still getting his water changes and maracyn oxy doses nightly.
