I fed my Silver Dollars Corass a while back - a mix of 4 sinking wafers... not my everyday staple, but they seem to love it. Being vegetarian, I figured they'd go crazy for the green algae ones (can fish even see all colors?), but they're just as happy munching on the red, green, brown, or black ones (each has different ingredients).
Anyone tried these? Got any thoughts? I've linked the ingredients for each color... my Silver Dollars swim around with them in their mouths, like they're snacking on cookies. The Tin Foil barbs, Hill Stream Loaches, flying Fox, and plecos (the ones without teeth) suck on them as they soften... 75% of my fish are hooked on these. The tetras and Denison barbs don't touch them, but I'm guessing that's more about mouth size than taste...
