Yes I believe it has gotten bigger. Maybe more dense looking, if that makes sense. Could it be an internal parasite? From what I can tell, it seems to be in the meaty part of the fish.

I got these. Working on better.

Thanks for the information. I have the kanaplex on hand. Just ordered the jungle fungus clear. It will be here friday. I have been watching this fish for awhile now. Like 3 weeks this gray spot has been visible. Pics don't show it but sometimes it looks like it is inside the body? But that could just an illusion. Its active and eats everytime food is offered. 75 gallon tank Water parameters Ammonia 0 Nitrite 0 Nitrate 5-20 API master test kit I cant tell the difference in the oranges in that range PH low 7's I dont test gh/kh. I have really soft tap water. Like 40ppm Tds out of the tap. If anyone else has any ideas, post them up.

Is this what I think it is? Columnaris? Its just this one rummynose showing a cloudy body. Little buggers are hard to get a decent pic of.
