I am having trouble with feeding my new 9" tiger oscar. He is the dominate one in the tank but he is not quick enough to get the food that I put in there for him. I have tried several times but I keep ending up with a morbidly obese RB Pacu and a quickly shrinking oscar. what can I do to make sure that the oscar can get some food instead of the pacu? Also, the tank is difficult to access because of the way the canopy is designed so reaching into the tank with anything will be a last resort. I will try to get some pics of them up soon. thanks in advance for your help.
