I have found a way how to keep oscars and plants together! Buy young oscars, and put them in an aquarium that has Vallisineria spiralis planted all over the aquarium. As they grow, they will arrange plants their way, so you will get a natural surroundings, low amonia, beautiful aquarium, and, of course, happy oscars!

I've only had my tiger oscar for about 3 months and I love him dearly. I have 4 aquariums in my house now and my oscar tank is by far my favorite. They have such personality! The other day he really gave me a scare...I hand feed him but on this particualr day he decided to do an Evil Kneivel and jump out of the tank about 20 cm and bite my fingers! Since then we have made a game out of least I like to think he's only playing as long as I come out with all my fingers! :)

I have two Long Fin Tiger Oscars. My problem is that they only eat fish. I tried goldfish, but they brought Ich into my tank and nearly killed my hard to find fish. The solution: I now breed platys in a separate tank to use as feeders. They are from a known home and are not diseased, as feeder goldies often are. Now my oscars are thriving in their 760 liter gallon tank.

I want to comment on the issue about breeding oscars. This seems to be an issue of importance to oscar, well to me it was. I have had oscars for 5 years now and let me tell you it's not that easy to sex them. I never thought of baby oscars, until one day coming home from work, just thought I'd say Hi to my oscar pair. Good God, there had to be at least a couple hundred to a thousand eggs. You could not believe how happy I was. I immediately removed all the other fish, making sure the oscars would feel safe about the eggs. Waiting, and praying the eggs will hatch. The on the morning of the 3rd day, the nightmare happen. The oscar which was fanning the egg, decided to have dinner. I couldn't sleep for a day for so, and I kind of never stop wondering what went wrong. I started to get all kinds of information I could about this issue. The information I found out from several fish experts in pet store were: first of all, there could be two female and the eggs might have never been fertile. Second the chance of them being eaten up like that would have been decreased if I had taken out the eggs right after they were fertilized by the male. Now this would have meant I would have witnessed the whole egging procedure and immediately removed right after. Now I have separated the pair just because they almost killed themselves over this. They don't stay happily together after breeding is done. So now I have introduced another oscar, to one of the mating pair, praying this one is a male, and they will breed. I was told from the pet store, oscars can breed again anyway from a week to several weeks and several months. Well all I can do is try over again and wait patiently. Good luck to all you out there breeding oscars, hopefully if you have any clues to this wonderful process of breeding let others know.

Oscars are great fish. They are fun to watch. I have an albino tiger oscar and a tiger oscar. They get along great and eat a lot. I have found out that once another fish is in the tank they want to pick on him except for the pacu I had with them until he got too big for the aquarium. Some great companions are Jack Dempsey's, Pacu's, Pike Chichlids, and Green Terrors. All of these fish eat goldfish so it makes it easy to feed them all at once. Oscars are great pets as long as they're in a big enough tank.

I have recently purchased two Oscars, one albino, and one tiger. They are the most human responsive fish I have ever seen. They do require a lot of filtration. In my 200 L tank I have an under gravel filter (which they haven't bothered), a Whisper (which isn't the greatest filter), and I also have a great Aquaclear 500. They love to eat frozen bloodworms and anything else you have laying around. They like to play with toys and enjoy keeping busy. My Oscars have all learned to jump out of the water and take food out of my hand 10 cm out of the water. To make sure that my ammonia levels don't get to high, I acquired a little gadget that sticks on the inside glass (in the tank) that turns colors if the ammonia gets too high. I have never had a problem with ammonia, and if I ever do, I'll be ready.
