look buddy, youre not posting pictures or anything. its really not that easy to figure out what youre talking about when all you say is a white spot. You could be describing tons of things but we cant figure it out. You cant say that people dont know what they are talking about when you have no clue whats going on either. how about you take a picture or find a picture of a fish that has the spot similiar to yours. then we can actually have something to go off of.
And a fish "curing itself" isnt an option as you seem to know. If it is a disease,parasite,fungus etc. it is probably just going through its life cycle
wow...what started as a simple question has gotten out of control... please let me try to make a couple of points:
1) no pictures can be taken at this time since at this moment none of my fish have this mysterious white spot and two I can't find pictures of it anywhere which is why I asked the question in the first place.
2) somehow the fungus idea was brought up even though my first post stated that this spot goes away on its own and never infects more than one fish at a time.
3) once the fungus idea was mentioned, I tried to point to out that it cannot be since I have never medicated the tank.
4) I got frustrated when someone said, "Re-read my post" and they obviously hadn't read mine to start with.
5) I offended some by saying they had no clue without admitting that I didn't either...but in my world, asking a question, by default, implies that I don't know the answer.
6) I apologize for the offense...it certainly was in bad taste and I learned a lesson from it.
