With the hole in the head disease, wouldn't there have been some visible sign of illness? I mean, the three fish I have lost all looked perfect. Beautiful coloring, fins perfect, scales perfect.
As to my hospital tank, I have so few times that I've used it and my Betta is perfectly fine. I also separate with separate filtration (I have a double filter) that it works fine for the purpose intended. But, no, I would never put a visibly ill fish in there...the only other illnesses we've had have been swim bladder type issues, so I have never really had a communicable disease to worry about.
Also, this is a Newbie forum, so being rude does no one any good for the poster who said, "so, let me get this straight...you put a sick fish in with other fish." Better wording to help might have been, "its not normal to put..." "Here are some other ideas to keep a hospital tank running..."
So, back to the post...why is it a gourami problem lately, and why are there not visible signs of an illness for us to know what it is? Is there any other illness that would cause a curvature of the body, lack of swimming, and floating?
Thanks all for your helpful replies.
