This is probably the most common cause of fish spitting out food in the home aquarium. It indicates that the food that you are giving them is either too hard or too large for them to eat in one go. Before doing anything else first you should check the water quality of your tank.

Oscar fish There could be several reasons your oscar fish is not eating food or spitting it out. You should check for ammonia levels oxygen levels temperature ph and hardness of your water. The ideal water parameters for oscar fish are as follows There are a lot of options out there for fish. He ll love brine shrimp freeze dried blood worms freeze dried baby shrimp and cichlid flakes or pellets. Mix it up a bit. I feed a little of this and that to fish. You should try to emulate a fish s natural diet as much as possible. Oscar s are omnivorous so they diet should be rather diverse.
If that s around 60 ish us gallons then no it won t last a few years. You got a year at best depending on foot print. Oscars are messy eater so spitting out excess food is normal. You could try a smaller pellet so he won t do it with pellets. Oscars need a minimum of 48x18 inches for one by itself not counting tank mates. My 4 inch oscar spits out his pellets about 60 perceent of the time and part of the time he does not even eat. He is with a 5 inch common pleco. But they get along fine. The tank is clean.
He dosen t have hole in the head. Hopefully he dosent get hole in the head like my oscar who died.i got him Well about a week ago i feeded my 7 inch red oscar a cube of blood worms and when he was eating it he put the whole thing in his mouth and ate it and ever scense that happend when he eats you can see something red come out of his gills and back in i don t know what they are called . And now when he eats some food also comes out of his gills. Hunting by spitting requires great control over the water jet shot at prey.
