Bleeding heart tetra darkened body coly

I just noticed one of my bleeding heart tetras has changed colors and looks unwell. His body should be clear but is a dark gray color.







This is one of the school that is healthy Today I did a water change as I always do on Sunday, about 20 gallons. My water parameters are all good. What is wrong with him?




this is the other side of his body, the whiteish parts are what's left of his natural color.

 

He does not appear to be in good shape, he is at the bottom of the tank I do believe I will lose him. I have no idea what happened to him....

 

found him dead this morning, since I got no answers I'll assume no one knew what happened.

 

Sorry you lost him. It's always sad when we lose fish.

Since there were no outward signs of anything such as a fungus ich etc. it's very difficult for anyone to diagnose. So I'm sure that's why you didn't get any responses. I know I had no idea's on what could have been wrong with him.

A couple weeks ago one of my Millennium Rainbows died. One day he just lost all of his color and was dead the next day. But other sudden loss of color he had no other symptoms. Sometimes it's just a fishes time to die.

 

Yeah that's what I figured, its just so frustrating I am so OCD about a clean tank, and clean everything lol. I look at and count my fish pretty much every day so I know when ones missing, or sick. He was fine the day before, and then yesterday he was just this weird blotchy gray color, no ich, no fungus, and he wasn't swimming well. Then today dead. Whelp guess I'll never know so onward I go lol

 

I'm sorry for your loss. Was this a new fish or did you have him for a while?

 

I have read of this species coming in from the wild with a "mold" present which kills the fish.

Are yours wild fish?

Is the disease on the fishes skin or somewhere inside the fish would you say?
