Hello guys, Unfortunately, I believe I am dealing with both gill flukes, and hexamita protozoa in my discus fish, unfortunately.. I could see them flash their gills, and some look somewhat skinny and darkened discolored, but they eating nicely, and not hiding much at all except when the lights are off and when it is really dark.. As of late, I perform about 100% water changes about every three days to help remove stubborn flukes and I retreat the tank with prazi; and also making absolute sure that the new water returning to the tank is extremely close to the tank's temp. So far, no problems with water changes. I'm currently feeding metronidazole medicated flakes to fight hexamita along with a high temp of 86F to help increase metro's effectiveness. So I just managed to get some Ich Attack from the LFS, and I was wondering if it can be used in the tank when it has some prazi that is active currently inside? Or should I just wait until prazi becomes inactive after a few days, or do a large water change to remove any residual prazi and then dose ich attack? Hopefully ich attack and prazi can be combined.. ich attack is organic and herbal, soo it's safe, eh?? But ahh just because ich attack is organic and herbal... Maybe there will be issues with them mixing and creating toxic conditions, or maybe it will put too much strain on the fish's system..?? So I'm still a bit skeptical and unsure and I want you guys opinions. I would appreciate any input or ideas, thanks a lot guys.
