Dying cardinal tetras!!! Help!

[kendrick_86]

Just return back from camp... found three dead bodies from in my tank last night.. then two more cardinal isolating itself from the rest. i found some white spot on it and noticed that the mouth open and close at a very fast speed. Think the fish got trouble in breathing. May i know how to cure it before more casualties arrives? thanks bro...

Try the cheapest way, quarantine all of them in a container, add fish salt (dose : 1 teaspoon / litre water) for 30 minutes max.
You can search this method from the forum...

Hi Kendrick,
The likely culprit would be Ich, aka whitespots. Try waterlife protozin quite effective against the outbreak but do take note of the medication's dosage regime which is spread out over a week.

First, set up an isolation/hospital tank. Fish out those afflicted cardinals. Use Protozin to treat them, like what Michael has suggested. Apart from treatment, do some tank maintenance and clean out the filters. The problem with ich is that it returns back frequently when treatment is incomplete or when water conditions are poor.

Tanks that have had a problem with ich should be fish free for at least a week during which the tank itself is treated with the medication.

The parasite itself has several stages in its life cycle, so the tank should remain fish free during the treatment period. This prevents the parasites from re-infesting other fishes in the tank.

My personal choice of medication would be Sera Costapur, but Protozin works just as well. Good luck.
