hey! well, your girls might be piggy and try to eat the food. I'd suggest distracting them with their own food as best you can while you drop the cories' food in there. also supplement with veggies. my girls don't seem to go for vegetables. You might also feed them on opposite sides of the tank.
Hi Bekah. :D I'm getting Corydoras for my sorority and Sakura said I might have trouble feeding them.. She suggested for me to ask you advice so here I am! So, any tips? BTW, the chat yesterday was disgusting.. I figured out why Teeney wanted me to close my eyes... >.<
