I think my barbs have popeye. Almost half of them are sick. I am going to use Mardel Trisulfa. I have checked a lot of info on the web, but I am still confused about one thing. It is recommended to put all sick fish in quarantine tank and tread them with this medication. If the problem is bad bacteria in my tank shouldn’t I thread my main tank with all the fish instead? It doesn’t make sense for me to tread the sick fish and put it back in my main tank. Has anybody used this medication? Will this stress the rest of the fish?(I have to use it for 5 days) I prefer to loose the half of the fish than all of them because of the medication stress.
Thanks for advise.
