Just found this thread.
I lost my baby Trinette suddenly this morning. I posted threads about her, thinking she had dropsy, but the generally consensus of the members here didn't see her pine coning.
I did treat her with fungus clear for 4 days last week and she was just fine during treatment and after. Fed her last night, she was active and happy, then this morning just gone.
I did not think to take a picture, i was too distraught. She did not have the silver/grey on her fins, but her right side was black, like something rotted inside of her, her stomach was slightly bloated making her head tilt upward and she was covered in furry white stuff in only 8 hours!!! I dont know if its the same thing, but 8 hours seems quick.
