Fry problems

[Julionz]

I seem to have problems with my fry each year. Symptoms are the same - gills open, near the surface and an emaciated look. My water is good - spring fed but the young get some of the water from adult tanks. Is this gill flukes?

Probably, you should treat.

Any fish with prtruding lower jaws, them flukes are confirmed

OK - thanks for that. I have 4 1000L tanks that feed into each other from a spring - do I need to empty them all and treat all fish or what would be the best way of dealing with this?

[suphi]

I'd treat the whole thing, for a peace of mind. Prazi is very benign and won't hurt your fish.

^Also, think about secondary infections (usually bacteria) if fish do not improve with Prazi.

[Julionz]

again thank you. I live in New Zealand and fish medications are pretty much non-existant. I have some Prazi from my vet - they recommended 28ml/100L - does this sound right?

[Cincy Ranchu]

That is an acceptable treatment, but I offer a couple areas of concern;

make sure the tanks are filled to the rim as fluke eggs can be an issue and I would trteat three times over a three weeks to break the hatch out cycle.
If the prazi is dry, mix with a little vodka prior to adding to the water
