growing

Question
i have brought a tiger oscar before a month(1 inch size from mouth to tail) and  am feeding blood worms to it,but still its not growing ,i mean bigger in size, why what's the problem with it?and how to make it grow.

Answer
Hello,
You did not mention the size of your tank.  One oscar needs a 55 gallon tank all to himself to grow healthy, and happy.  If he is kept in a tank smaller than this, his growth is will be stunted, and his internal organs have no place to grow.  He dies a horrible death.  If this is not the case, an Oscar needs variation in his food.
Here is a list of foods that the Oscar should have:
A good quality flake
A good quality pellet
Frozen veggies bought at the market, and blanched, then cooled.  (Peas, green beans, broccoli, carrots)
Spinach, and leafy lettuce
Earth worms bought at your bait store, and cleaned.  ( To clean the earthworms put them in oats for about a week)  Buy them at the bait store so you will be sure there are no pesticides in them.
Minnows, bought at your bait store.  (Buy the regular kind)
Crickets bought at the Pet Store
Frozen bloodworms, brine shrimp, Plankton found at your pet store
Frozen fish, that you unfreeze before feeding this to your Oscar.  Fish that you find at your market which is frozen, and comes from lakes, and rivers, never from salt water, only rivers, and lakes.
Bananas, and Mangoes, now, and then.  No citrus fruit.
Never feed him feeder fish.  These fish have no nutritional value, and are almost always full of disease.
I hope this helps
