Ok, so I guess there is some good news and some bad news.
So, the white stuff covering everything has not reappeared. :)
Yet, the water is still hazy (so I am doing a partial water change again tonight, this time more like a 35-40% water change).
My fish seems to be very active so, I'm happy that he seems happy.
I'm still testing my water for nitrites and ammonia and things are still good.
Now, one weird thing I've noticed. My fish has these dots on 2 of his small fins (the small ones near the front - more for navigation/propelling I guess). He's always had them from the day I got him but I am wondering if it has gotten a bit worse (if it has, it hasn't gotten worse by much).
I can't get him to stop moving for long enough to take a clear picture so I tried to do my best to make a drawing of what it looks like close up. I'll be posting that here as well as in the diseases section to see if it's something I need to worry about and if something can be done.
Yet once more, thanks again. :)
