Feeding Your Oscar Fish

Probably second most important to housing your Oscar in a suitable aquarium is feeding it on a healthy and varied diet. Oscars that are fed on a poor diet may go on to develop illnesses and disease later in life. One such nasty ailment is called hole in the head disease and is directly related in part to unsuitable food fed to the fish.

A healthy and varied diet

Oscar fish should always be fed on food that is good for them. We would recommend that at least 80% of the main diet consists of a good quality Cichlid pellets. There are various different manufacturers that produce really good quality food that is packed with all the nutrients and vitamins that your fish need on a daily basis. You can then supplement the rest of the Oscars diet with other types of food. Some people like to add a lot of natural food that is close to what the Oscar would feed on in the wild. Oscars eat a lot of insects in the wild so feeding them on live food like crickets, locusts, grasshoppers, mealworms and even garden worms is good because all these foods contain vitamins. Seafood is also healthy and a great supplement for your Oscars diet. They love cockles and mussels, obviously minus the salt and vinegar. Prawns and shrimps are absolutely fantastic food as they contain a lot of fibre which can aid the Oscars digestive system. Try chopping up pieces of fish such as tuna or salmon. You can even feed your Oscars on pieces of squid, they love the meaty texture of this seafood.

There really is a massive amount of food available, especially if you visit your local fish store and have a look in their frozen food section. Visit our food list article for a much more in-depth list of what foods you can give to your Oscar.

How much and how often should I feed my Oscar?

There really isn't anything to worry about what it comes to feeding your new friend for the first time. Baby Oscars are absolutely voracious eaters and seem to be hungry all the time. However, there is obviously a limit on how much they should be fed and I'll explain how I've been doing it for the last few years.

If your new Oscar is just a little baby then it is advisable to stick with fairly small foods, to begin with. I certainly wouldn't be putting in large prawns, or even very large pellets because baby Oscars are incredibly greedy little individuals and will more than likely stuff as much as they possibly can into their mouths. When this happens they often have problems swallowing the food. Cichlids pellets come in three or four sizes, I would advise starting off with the smaller sized pellets that are available. Start off by dropping in three or four small pellets, to begin with, and let the Oscar eat them. Follow this procedure for about three minutes and then stop feeding. Keep this feeding regime until the Oscars reach about 5 inches. Obviously, in the meantime, you could increase the size of pellets. There's no need to put a stopwatch on, three minutes is really just a ballpoint figure. You may find that the Oscar doesn't want any more food after three minutes. Normally the Oscar will indicate when it's had enough. However, baby Oscars are very greedy and it's very easy to get taken in by them. Don't be fooled by their constant need for food, these guys can beg like a pro, which is why people often overfeed them.

Oscars that are 5 inches or more don't necessarily need to be fed three times a day, you can reduce feeding down to twice a day. Carry on the same routine, as much food as they can eat in about three minutes. Once the Oscar reaches 10 or 11 inches then you could feasibly feed it just once a day. However, most people would prefer to feed at least twice a day. If your fish leave any food floating on the water remove it before it starts breaking down.

Beware of some foods

There are some foods that we would recommend you avoid feeding to Oscar fish. Some food items may contain parasites and disease, whilst other types of food either don't contain many nutrients or more worryingly contain high levels of saturated fat which are very bad for fish.

Feeder fish

The term "feeder" fish basically refers to any small fish that is used as live food for another fish, normally a larger predatory species of fish. The most common species people use as feeders are goldfish. The problem with goldfish is they can contain internal parasites that if ingested by your Oscar can cause all sorts of problems. No one is disputing the fact that Oscars will probably be an opportunist in the wild and will certainly eat any other small fish given the chance. However, we feel that it's a risk that is not worth taking so feeding live fish is best avoided when there are plenty of other better and more healthy foods available. If you are absolutely adamant that you want to feed live fish to your Oscars then we would encourage you to either breed the fish yourself or quarantine any purchased fish for at least two weeks. But that will never 100% guarantee you are not feeding infected fish to your Oscar.

Animal meat

You should be very careful what type of meat you feed to your fish. Most animal flesh contains saturated fat which is very difficult for a fish to digested properly. Fish can actually develop something called "fatty liver disease" if they are fed on meats with a high fat content too much. Once again, if you are absolutely sure that you want to give your fish meat then we would advise getting properly prepared beef heart from the fish store. This is very lean and should not contain hardly any saturated fats. However, this shouldn't be fed more than a couple of times a week. Personally, I would advise that if you are going to include beef heart as part of your Oscar fish's diet, also include shelled peas as this will help with the digestive process.

Commercially available fish foods

I've compiled an extensive list of commercially available foods that are available. I'm very sorry, but I can't guarantee that all of these foods are available in your country and at your fish store, you will just have to ask. However, you will see that a lot of the list items are text links. I've searched out items to make sure they are available on eBay and linked directly to the products. If they are not available at your local fish store then hopefully you can get them off of eBay.
