Cardinals Not Exactly Liking The Flakes
So, my school of 6 cardinals acclimated themselves overnight, but they are not exactly interested in the flake food. Neither are my swordtails - at least the swordtails eat the flakes - and the algae wafers... But neither will go to the surface and eat like a good fishie. I tried sparking the instinct by tapping teh surface, I fed them brine yesterday, but I'm out of ideas. Please help.
