A mainstay of oscar tanks is driftwood. The tanins in the driftwood tend to buffer the water to the lower pH range that Oscars prefer. Also, driftwood sold at retail normally is attached to heavy pieces of slate, so it is difficult for the Oscars to move it. Finally, plecos, which are a common bottom feeder in an oscar tank, like to scrape on driftwood.
Another good decoration is large river rocks. They tend to be smooth, so the oscars are not likely to injure themselves if they bump into a rock. They also give the tank more of a natural look. Finally, every fishtank with egg-laying cichlids should have at least one piece of slate. This gives the fish a flat surface on which to spawn. If they do not have a convienient flat surface for this purpose, you will often find that they have dug spots in the gravel all the way to the glass.
Your Oscar will toss these around almost like playtoys. Without a weighted base, most plastic plants in an Oscar tank will spend their time floating at the water surface. Oscars are known jumpers. A lid or some kind of tank top is necessary to prevent your Oscar from jumping. Do Not train your oscar to jump out of the water for food. Too many Oscars leap out of their aquariums and either fall to their deaths or lie helpless on the dry floor.
Unfortunately, you do not have to train some Oscars to do this, they just will. If you suspect that your Oscar is a jumper you need to weigh down the lid. Put some books or something heavy on the lids. The big debate between substrates is sand vs gravel. Either substrate will suffice for an Oscar. Just remember that Oscars like to dig. Fine sand can work its way up into a filter and ruin it. Sometimes right into the filter intake.
Be sure and use a pre-filter on the filter intake if you have sand or there is a good chance it will be damaged by the sand. More on gravel vs sand here. Especially with gravel, uneaten food and debris will work its way down into the substrate so if I am using gravel I prefer a shallow substrate bed, 1 — 1. Others prefer a shallow sand bed. If left undisturbed, sand will allow gas build up from nitrogenous waste that is potentially dangerous.
Sand needs to be stirred up so this gas cannot accumulate. There are others still that prefer no substrate at all. Bare bottom tanks are becoming more popular due to the ease of maintenance.
It's what removes all the toxins from the water and keeps the fish alive. Without biological filtration, your fish would be swimming around in a toxic soup.
If you are using a canister filter then you will probably find it came with some strange -looking bags of material that either resembles little round balls, or little rings that look a bit like pasta.
This, in fact, is your biological media and will be contained within the trays in the filter. This type of filter media is very porous and therefore the nitrifying bacteria have a really good surface to live on. The big advantage of using this type of biological media within a canister filter is that it really does an excellent job of dealing with ammonia and nitrite. Secondly, if you don't overstock your aquarium then you can often leave canister filters for longer intervals in between cleaning.
You may have noticed a black sponge in your filter. This is what is called chemical filtration and it's designed to remove impurities from the water.
The best use you can get from using chemical filtration is to remove any medication that is left over from a water treatment. Some people use it in order to stop their water smelling. However, the problem with chemical filtration is that eventually, it will become completely saturated with impurities. If this happens then there is a possibility that impurities could start leaching back into the aquarium water. It's up to you whether you use chemical filtration. If you do use it then be aware that it needs replacing every few months.
There are only two types of filter I would recommend for an Oscar fish aquarium, and they are a large canister filter or a sump filter. Because Oscar fish require large aquariums, small filters are of little use because you would need about three or four of them installed in the aquarium.
Even then, you probably wouldn't have adequate filtration. There are numerous different manufacturers of canister filters that would do a great job in your aquarium. If you've got the money then I would recommend Eheim as they produce the Rolls-Royce of aquarium filters. Yes, they are expensive, however, you get exactly what you pay for.
Eheim produces canister filters that will filtrate aquariums right up to L, which is about gallons. I've used Eheim filters ever since I got my first aquarium and I think they are just fantastic. Another make of filter that a lot of people highly recommend is Fluval.
They also produce good quality canister filters that are more than adequate for filtrate in a large aquarium containing Oscar fish. Because Oscars are so incredibly messy it's a good idea to literally double the filtration on your aquarium.
If you've only got the one adult Oscar in a gallon aquarium then I don't think there's any need to go over the top, a filter rated for a gallon aquarium would work just great. When I had my gallon aquarium I have a couple of Eheim canister filters installed, both of which are rated up to gallons. But I had two Oscars and a few tankmates and the extra filtration was well needed.
The beauty of having two canisters installed on the one aquarium is if one breaks down, you've still got a working filter that will still keep the tank clean until you get the other one fixed. Also, having to filters means that you can alternate filtration cleaning. This means that you are not cleaning both filters at the same time risking losing bacteria.
You can clean one filter one week, and then wait another week and do the other one. Canister filters normally come with a spray bar that resembles a garden sprinkler. The spray bar is attached to the side of the tank and should always be placed just above the surface of the water. What you are aiming to achieve is a constant water surface movement created by the water spray.
It's important that your fish have plenty of oxygen, setting up your spray bars properly will create this surface agitation and in turn creates lots of little oxygen bubbles. When a fish tank hasn't got enough oxygen in the water the fish will normally breathe fairly heavily. If the oxygen depletion is particularly severe then the fish may hang at the surface opening and close their mouths whilst they take in oxygen.
If you're using a good filtration system then it should oxygenate the water properly. However, if you feel that you want to add oxygen to the water, maybe because the weather is warm then you can use an air stone. But avoid exposing them to direct sunlight.
It may cause harm to your fish. Also, you should fix a non-flashy light in the aquarium tank. It should be as dim as possible. As said earlier. Oscars need a heater in their aquarium tank, to help regulate and maintain a constant temperature.
In the wild, Oscars survive without the use of a filter. This is because they have adapted to the environment. However, you should fix a filter to your home aquarium. It will help remove excess waste and ease water change. You need to put a lid on your aquarium tank. Oscars love to jump around an aquarium tank. So, you will need a cap to prevent them from falling. However, you should get a transparent cover. Although not often, Oscar may require some moment of isolation from other tank mates. For example, during the breeding period.
Moreover, Oscars love to play at the bottom of the tank. So, you will hardly find them on the surface. You should avoid transporting your Oscar often. But, consider if the environment is in the same condition as its first home.
However, make sure you place it in a temporary home while preparing its new home. Also, you should carry out these processes as fast as possible. Maintaining an Oscar tank is a significant contributor to the health of your fish. When ammonia, nitrites and nitrates level is zero in tank, your water tank is fully cycled. Start by floating plastic bag in your water tank to make the water temperature of bag and tank water as same. It takes 20 minutes of time and then you can add your fish in a water tank by acclimating your fish to pH level of water tank.
Ammonia and Nitrites Levels should always be maintained at zero level in case of Oscar fish water tank as these chemicals are toxic to your fish. Levels should strictly be zero because their deviation from zero value may result in death of your fish.
Oscar looks cute, sweet and appealing wiggling its nose in the water tank when you buy it from a local fish store. This is when you buy Oscar of about 1 to 2 inches long, but unfortunately it grows up into large, mean cichlid surprising you while they swim across the entire tank with some catfish in the corners of your water tank.
Though they differ in colors, but they all are same in terms of their feeding choices as they prefer meat either in the form of frozen food or pellets. So, they make a real mess producing a considerable amount of waste in the tank and hence, requires a canister filter for filtration process. Breeding process is easy as long as a female is not killed by male. Oscar fish tank size in gallons, varies as per their size, but in the general case, it is minimum 55 gallons for a single fish which is typically about 10 inches in length in captivity.
