Hi All,

I got home last night from work to find my usually very healthy male A.biaeniata laying in a bunch of wisteria near the surface of the tank struggling for breath. When I looked closer he had a really big fungus outbreak coming out of one of his gills and a little patch on his dorsal fin.

There was no way he was going to survive much longer so I had to euthanise him.

But I've never seen anything come on so quick like that. My wife and I are both pretty sure he was totally fine the previous day.

I'm guessing the fungal growth was a secondary sympton of whatever had hit him, but I can't figure out what could effect him so quick and lethal.

Any ideas? No other fish are looking sick or bad at all.

Regards,
Peter.
