feed the same food? I ask because I have a 30gallon long with Gouramis, Glowfish & Misc.Tetras in it. They eat tropical flakes. Is that bad for the Fancy Fan-Tail Ordanas & Koi to eat that too? I also feed my fish frozen Brime Shrimp 3-day's a week. Also throw some Frezee-dried blood worms in about twice a week.
