Had some bad things coming from my Dwarf Gouramis the other day and I started doing some research into parasites. I'm going to pick up some Sechem Metronidazole tonight to feed all my fish as a preventative measure. Supposidly, it is plant and shrimp safe if used as directed.
Anywho, I called and talked to a guy at fishyfarmacy.com after seeing their site info regarding parasites, etc... I have no idea how reputable this company is and who knows what my DG's really had but I found his opinion of food interesting. I told him one of the few foods I use is New Life Spectrum's tiny pellet food. 3 of my LFS' use this exclusively.
He said he never recommends pellet food because it is a pressed food and when a fish eats them, they then swell in their stomach, which causes all kinds of problems. He said he is a doctor and they have their own lab and constantly runs tests, etc... and they disect a lot of fish to research food, disease, etc.. He recommends frozen, live and flakes. I also feed flakes and frozen.
Again, I don't know but would like to hear some opinions.
