Crap, can't seem to upload any pix since my phone connection seems to be broken. I'll just give as much detail as I can.
For 3 days I've been observing him, the cloud seems to be growing from covering the bottom now covering half of the eye and his poop looks different from the one he always release, it looks like a string of white. Doesn't seem like a worm to me but it's so alarming.
So far he's eating as always. Fed him some raw shrimps and some worms just to bulk him up and build his strength. Putting 1 spoon of medication in the tank every morning and doing no wc since the LFS told me to do so.
I'm so confused right now and I don't know what to do because I've been to 3 LFS already and their instructions doesn't fit to one another.. So do I really need to do a big water change because the LFS here told me that wc is not necessary since the medications will be wasted but the other LFS that I've gone to told me that before medication, I must do about 25-50% water change but didn't recommend any salt treatment since they said that salt will only be used if there is a skin problem. If wc is really necessary before applying medications then I'll do it tomorrow.
