cory's have no issues with the planted tank.
plants don't 'eat' left over food...the food breaks down into nutrients (nitrate and phosphate) and the plants consume that. So if you're over feeding, you'll still have food to vac up. Nothing special for the fish if you keep plants, but they may uproot plants from time to time.
Now, is this micro 'chain' sword? Does it look like this
If so, my main concern is if you hae enough light. That plant requires 2watts per gallon minimum, and CO2
injection to do well.
