For water changes, if you don't have one, you should get a python water changer. It makes draining and filling a large tank so easy. It hooks up to a sink faucet on one end and has a gravel vac on the other with which you both drain and fill your tank. I think most people don't keep up with large water changes often enough because it's a lot of work with 5 gallon buckets. Here's a vid on how it works.

Guys, first a water testing kit is expensive in my country. Second, I can only water change during the weekend. Third, I think water change is stressful to my fish.

First: Too bad. You can buy an API freshwater test kit online from Amazon or ebay for a reasonable cost. It's something you need to take proper care of your fish, if you can't afford it you can't afford the fish.

Second: I doubt you can't spare half an hour during the week to do a 50% w/c. Otherwise, you'll have to do big w/cs on the weekend then.

Third: w/cs are a lot less stressful than keeping your fish in such poor quality water it's literally half the size it should be.

You wanted to know why your O was so small and now you do. Making excuses as to why you can't fix what's caused the problem isn't going to make the problem go away, nor are those excuses going to absolve you of the duty of care you have for your fish that you are not upholding.

If you're that short on time and money I'd suggest re-homing your fish before they end up with more severe health problems.

Isn't water change once a week?

Water changes need to be often enough to keep nitrates below 20ppm. You need a test kit to figure out how often that needs to be for your fish. We rec the API freshwater kit because it's the most reliable. Strips in particular are useless and inaccurate. If you keep your water clean it doesn't matter if you do one really big water change once per week, or multiple smaller ones during the week. If you let your water get really bad (as you've done) you need to build up to it - 20% one day, 40% the next, 50% the day after. Give your fish a chance to adjust to vastly different water parameters.

I do one 90% water change per week for my red devils, and 2 - 3 60 - 75% water changes per week for my oscar tank. It equals similar water quality (nitrates <10ppm for both).

I heard this before it takes 1 hr to let the water conditioner settle before adding it to the water or else it will kill the fish. Is it true?

I don't know about other dechlorinators, but no that is not true with Prime or Safe. I add it immediately before filling using the python hose with water from the tap (temperature approx. matched).

Most dechlorinators are expensive, yes. One container of Safe lasts a long time though because you don't need to use much each w/c. As with the test kit, if you can't afford dechlorinator you can't afford the fish.

The problems you are running into now are exactly why it's emphasised to do your research before owning a fish like an oscar. You've got a fish that can get over a foot long in a glass box that is prone to health problems if it has less than pristine water. It's a no-brainer that keeping a fish like that will take a lot of work, time and money compared to other fish.
