Feeding Frenzy

Question
problem.... i have a tank full of fish i soon plan to get a bigger tank and split them apart. but i have 7 oscars all about 4inches 5 jack dempseys all juveniles at about inch, 2 Red Zebras, 1 Green Terror, and a crayfish. the problem is when i feed my fish the oscars bo-guard and eat up all the food whether it be prepared foods or feeders. i just cant seem to get the food to other fish. what do i do

Answer
What size tank do you have?  A single oscar needs 55 gallons and most need to be kept along.  the 5 dempseys should be in a 55+ gallon tank alone...the red zebras green torror and crayfish should be in a 55 gallon alone.  The only solution here is to separate these fish into 2 55 gallon tanks...and a 150+ gallon tank...
