Ok, so I have been working on fixing up a friend's fish tank and I think I have finally figured out what this disease is in the tank...hemorrhagic septicemia so I've done some reading about it and I think I understand the basics, but I really need help! There is already a big tinfoil barb that died, although I'm not sure what he had. The tank is 75 gallons, stocked with 3 tiger barbs, one parrot chiclid, and one Pleco. I have been able to see all the symptoms since I started trying to figure out the problem over a month ago. Everything has gotten worse since then. I saw them before, and they looked stressed, but she says the problem really began when they tried to add a batch of glofish who mysteriously disappeared(probably eaten by the parrot)
But anyway, the tiger barbs are the ones where I'm really seeing the red splotches and lethargic behavior. One even flipped over for a second at the top last week. I'll add a picture.
The water parameters are
Ammonia, above0.5, less than 1
I don't know what they were last month when the problem appeared though.
So, my big questions are these:
1 where did it come from????
2. Is it contagious ?
3. Is it treatable at this point, or will I need to eutanize the fish.
Thank you so much!!
