6.5 to 8.3___________________
Oscars can be kept as said above in a wide range of PH, however they do best in a neutral PH as do most other South American Cichlids which Oscars are. (Neutral PH is 7.0)
hi im 13 ive had Oscars and are sensitive to nitrates you should be changing the water regulary and should have an air pump and they should have a big tank and not to many tank mates hi im 13 ive had Oscars and are sensitive to nitrates you should be changing the water regulary and should have an air pump and they should have a big tank and not to many tank mates
For now, yes. But you should consider moving them into a larger tank.
If a fish tank needs a pH of 5, but at present it is at 7, more H atoms should be added to the concentration.
I do
yes they can
If you have a well filtered and properly set up tank that measures around 8 feet x 2 feet x 2 feet you have a tank that is just about large enough for 4 adult oscars.
The Oscar fish naturally stay calm when they are in a pair.keeping more than two Oscars in the same fish tank can cause then to get aggressiveso keep two Oscars at the max in one tank.
The water in the tank that you are transferring the angelfish to should be the same temperature and PH of the old water.If you are adding them to your tank from a fish store, then you should acclimate the fish first by floating the bags in your tank, and every so often add a bit of your tank water to the water in the bag to avoid temperature or PH shock.
The temperature of an Oscar tank should be between 21°C and 28°C although Oscars will be okay with water up to 30°C. Too cold can result in your fish becoming susceptible to diseases and too hot would mean reduced oxygen in the tank. The optimum temperature should be around 24°C.
Oscars should be kept alone so they don't eat any of your other fish of fight with other Oscars. Oscars also grow very fast and as they do they become more and more aggressive. They can sometimes be kept with a large plecostomus if your tank has plenty of room.
You might be able to get away with it, but honestly i don't think it's a very good idea. The Oscars are likely to nip the fins of the koi. Oscars are much more aggressive
If you do the right thing by your fish it should not be dying. The basic rules for keeping fish are :- 1 inch of fish needs a minimum of 1 gallon of water (Oscars need much more). :- every tank needs a permanently running cycled filter. :- every tank needs to have at least 50% of its water changed every week.. Oscars need a temperature of above 75F and below 85F. One Oscar needs a properly set up 20 gallon tank. 2 Oscars can get by in a 30 gallon tank.
