The saga continues....

I treated some GF with Kanaplex for what I thought was Columnaris and the
Cottony patches subsided, but did not disappear. A few days later they
started to develop Septicemia and I thought I was going to lose the
largest fish. So I'm treating them with Marycyn II now and they are
looking better, but they are not eating well and the middle fish is very
listless. The smallest fish never developed any symptoms and still seems
fine. He seems to have an immunity to whatever is bothering them.

I really can't explain what's causing their problem as the water
conditions are fine, in fact the Nitrates are lower than I would have
expected. I think it must be a parasite of some kind, but I don't see any
indications of it. Any plant/filter friendly recommendations for a
precautionary treatment that won't stress the fish too much.

Bill, I seriously suggest you take the bigger fish and move him to another
tank.

You are at the top end load of that tank now and it will not get better.
The newer bigger filter may help but any situation where you have too much
fish, means their immune system is taking hits and it seems that's what's
really going on here.



I'd agree, except that the Nitrates are OK at the moment and all other water
conditions test fine. I suspect parasites were the original problem due to
the timing with the new plant, although there are no visible signs or
flashing. I gave them some parasite food today, but they just spit it out
because they don't like the taste. They feel the same about their medicated
food. :-) Maybe I'll try soaking some peas in some metronidazole, but I
expect the same response. I might try a single dose of Malachite Green to
rule out parasites.
