Weird fungal disease??

[brishe]

Our rainbow tetra stopped eating a few days ago and on wednsday went a dark colour around his head and eyes, then his eyes were really swollen like google eyes, if i looked really closly you could see small bits of skin hanging off his eyes and mouth he had white patches on his mouth. and his eyes were also cloudy. He would occasinally go nuts too and spin in circles and swin so fast around the tank you could hardly see him.

About a week earlier he was breaking out in sore as was the male dwarf gourami he is in with.( i posted under freshwater" Do Gouramis attack other fish", as i thought that this was what was happening, but its not, he chases him but i havnt seen him nip yet)

The gourami is also breaking out in sores but is otherwise ok.

I treated the tank yesterday with Furan 2?? and today his eyes are not swollen and he seems a bit more settled.

Sorry for the novel, but any ideas??

Have you checked your water parameters? Maybe something is a bit out of whack. If so I would do a good water change 30-40%.

I have never used Furan 2, but if its working and that's what it is designed for then keep using it as per the dosage on the packet, unless anyone else has experience with it and their opinion differs.

The ph has been stable at 7.0, the nitrite was up slightly, ammonia nil.

I have been feeding them medicated food for hex at the moment and its hard to get them to eat it all so probably why nitrite up but its not dangerous. Once furan finishes its course tommorrow them i will be doing a water change. Strange!!
