I had Great experience with this fish!! I rescued one from someone who was keeping two 6" oscars in a 10G tank. The one I rescued was the greatest fish!! Really smart, he knew a lot of tricks. I recommend at least a 75G for one though, they are active and If they didn't have enough room they bash against the side of their tanks, often breaking them! Also, High-quality submersible heaters are important, sometimes they show aggression towards heaters/filters and they can break heaters and electrocute themselves. Those Tetra-Tec filters with the heater inside the filters are a good idea. Feeder fish aren't necessary for their nutrition anything else. If you want to give them feeders, breed your own guppies(one fancy male, two/three fancy females in a 10G) because store feeders are very unhealthy and wrought with disease. IMO a high-quality pellets are plenty for their food. Small gravel also is a good idea because they like to dig. Plants are enjoyed as attack objects, but don't expect them to stay in place. Mine enjoyed a big rock to hide behind. They are messy so excellent filtration and often gravel vacuuming is necessary. I recommend at least double filtration(ex. 2 60G filters and a 30G filter on a 75G tank)

give these fish room and they will reward you. I keep 6 full grown Oscars in a 180 gallon tank and I have more fun with them than I do with the dog. Throw in a ping pong ball and watch them play . they all like to be handled and can do basic tricks like ring a ceramic bell for food. just give them room.

From: John
Oscars are the best, I recently started caring for to youngins, after hobbs died after 12 years of care . they are at times more playful than my Dalmatian, and easy to care for with enough room , plenty of filtration and a varried diet.

I have my Oscar in a 55 gallon tank. It is a tiger Oscar and he is housed with a clownknife, arowana, Jack dempsey, and parrot. They are all of relative size to each other(no longer than 6 inches) There is no problem in my tank what so ever.

From: Shawn M. McNamara
As read above, my Oscar is currently the largest fish in my tank, and it is defiantly not territorial. It seems to have mass respect from my four other Cichlids (Green Terror/Texas Carpintus/Managuense/Oscar). The tank is the Oscar's domain .. free to go where-ever wanted, with the occasional dominance stand-off with the Texas. Oscar is also a seemingly friendly fish .... loving attention when those are looking at the tank. A great fish!!!

From: Tiffany
I love my Oscars!!! I have 5; an albino in a community tank, and 4 tiger Oscars in a separate tank, and I wouldn't trade them for the world!!

From: Darin Soares
I have 11 Oscars in a one hundred gallon tank. I had them for 2 years and there all still alive.

From: Jennifer
Oscars are a great breed of fish to have, but only for someone who is willing to take the time and money to have them.. Because as they get larger, you have to spend more money on keeping the tanks clean (ex: filters), and it can get relatively expensive having to change them once every couple of week's (depending on how many you have (ex: I have 2 Oscars and 2 Jack Dempseys in one tank, and they are large so I have to change the filters once a week). And what I mean by time is having to clean the tank.. Taking out about 30% to 40% of the water each week, or they could get some type of fungus. Now, this is only what I have read, and my experience with them. I also raise Bettas, Black Skirt Tetras, Jack Dempseys, African Chilids, and ton's more!

From: Greg
My experience with Oscars has been wonderful. I have never come across a fish as intelligent and playful, or with such a personality. This is defiantly a fish that has been given a bad rap, and before one makes assumptions from things he has read, he should try having one for a while. With good filtration and frequent water changes, this Is a very easy fish to take care of.

From: Ivan
Oscars are great..!! I have two that I bought as babies they are easy to care for and very playful.... my girl just laid eggs !!!! I don't have to do all of the changing water and filters stuff that the other guys have talked about... just normal maintenance!!

From: Steve
I have just bought 2 oscars and they are great fun to watch, they are very intelligent and easy to maintain. They share the tank with a pacu and all get along great.

From: Jeff
I kept two Oscars for several years, in fact, they were the fish that introduced me to fishkeeping. So easy to care for and they were truly pets. They would eat from my hand and would play with a Ping-Pong ball. Just the best.

From: Darin Soares
I have three tiger Oscars about 10 inches long in a 180 gallon tank. They don't seem to mind the plants but they keep on fighting for every goldfish I put in.

From: Matthew
I currently have 6'*2'*2' tank housing 4 oscars 6 severums 1 hi-fin pleco and 1 golden-spotted pleco. I have reared all these fish up together and have no major problems with aggression(only a little during breeding time). I write about my full grown pair of oscars' now you might not believe me but they are bright yellow like a golden severums and are the have the best temperament I have seen in any oscars. All the fish can be hand fed and patted just like your run of the mill cat. I believe that oscars should be raised in a community setting so you don't get the nasty streak(of cause not NEONS etc.)' all so nether feed feeders otherwise any time you go to introduce a new addition to the tank they will think you just bought home a treat for them(These fish have terrific memories). Large water changes Benefit these fish as they are very messy feeders, I recommend at least a 25% to 40% water change weekly. In the wrong conditions these fish do become aggressive so if you have a grumpy oscar check your water conditions before you condemn them. If your Oscar falls Ill then Use a 1% salt dose(tank) or a 5% Salt mix(bathing) this generally brings them back to health. A oscar is more than a fish it is a pet that you can be loved and nurtured and in return will give you many cheerful moments
