Fungus

So our fish PEE PEE caught some sort of fungus from the tank... and so now he has to swim in green water...
He had white chunks of cotton falling off of his body... and basically looked like he had leprosy.
So, now we have to change the water every 3-4 days and put green tablets in it that look like they are cleaning dentures when they dissolve.

Hopefully with all this TLC PEE PEE lives and we won't have to arrange any funerals. I don't think he has a will done up!
