Oscar info needed please,

I have 3 tiger oscars roughly 5mnths old everything was fine up to 3 weeks ago but now they just lie on the bottom of there tank and at times they go on there sides, I have alsorts about this saying it can be a natural thing or that oscars are a lazy fish but I just need it clarified of someone who as oscars or who really does know what they are talking about. They feed ok and when I open the lid they swim up but soon fall back down to the bottom. I have a jewel 140 litre. Bow fronted tank so I have plenty of space for them and I'm running a fluval 303 external along with the juwel internal filter. Thank you. Any help will be much appreciated, I don't want to lose my fish. Ps. I have tested the phone and it's fine.

The problem is your tank size. It is not big enough for one oscar let alone 3. The water quality will not be able to be kept good. You need to do large 75%or more daily water changes until you can get a larger tank. 200 gallons if you want to try to keep all 3 which won't happen. It's next to impossible to get 3 oscars to live together once they get close to maturity. It's hard to get 2 to live together unless they're a mated pair. You need a minimum 55 gallon for one oscar a 75 is better. Even when they are small. They are huge bio load fish. If you can't get a larger tank soon, like with in days, then you will need to rehome them. They will not live for long like this. Trust me, I'm an oscar guy and this is not a sustainable situation. They are suffering probably due to high ammonia as well as the definite high nitrates.

My water temp is at 75 ezy thanks for your reply. And munre thanks for your valuable comments. It looks like I'm gonna have to rehome them because at the moment I can't afford a bigger tank, the aquarium I bought them as given me me a number steer regarding tank size and Oscar limits, not a happy man at all.

lol very true daryl my brother as had oscars before so I was silly to get the smaller tank knowing the size they grow to, and was even more stupid buying the 3 oscars.

Hi munroe. Sorry for mothering you, I have found the bill for my tank and it says on there I purchased a juwel 190 trigon. 190 litre water capacity where I said it was 145 in my main post, is 190 still to small for the 3 oscars, what would be your best advice please....
