I have pretty much exhausted everything I can think of except medicated food, so here are the details and I hope someone from the outside may pick up something that will work.
I have a fully cycled 135L tank with two Panda Moors in. It has two external filters, one of which is also attached to a UV sterilizer. The smaller of my Pandas has only been with me for 3 months and I have had problems from nearly the start.
Water readings:Ammonia = 0
Nitrite = 0
Nitrate = always between 5 and 10
Ph = between 7.4 and 7.8
Symptoms:She either floats, lies on the bottom, or lately floats upside down.
She eats well.
She seems lethargic.
She seems to be developing a curved spine, and swims more in the direction of the curve.
She either has long stringy poos, or none at all.
Sometimes she passes huge bubbles alone, and sometimes in her poo.
She has also started swimming with her head further down.
What I have done:Tried various food, and kept a diary, and there doesn't seem to be a correlation except with one.
Increased the temperature slightly (It had a marked positive effect for a short while).
Fed a pea before every meal.
Removed all dried food for a while giving only homemade gel food.
Put Epsom salts into her food when it was bad.
Tried a flake soaked in Glycerine.
Epsom salt bath.
Fewer and then more frequent water changes.
Fasting her for a day or two, then feeding with a pea.
Used Droncit to deworm and defluke.
Conclusion:When do I have infinitive proof that this is an infection to treat with medicated food?
My other fish with her is perfect.
I have read the article on Swimbladder problems on here, which I found very interesting, and I have tried everything on there. She seems in pain, and it is stressing me out. Any advice would be so thankfully received.
